July Stats Roundup

This post is part of a monthly series summarizing some stats and figures from the Akismet universe. Feel free to browse all of the posts in the series.

In July, Akismet saw 5,608,437,500 pieces of spam come through. If each piece of spam were a book, there would be enough books to fill 156 Libraries of Congress (the largest library in the world).

There was a small increase in spam numbers since June – about 5%, but a 71% increase from last year in July. That’s about the same yearly increase as the one was saw in last month.

We also saw 310,275,000 legitimate comments made, which makes up only 5% of the total comments we see going around. If each real comment were a book, there would enough to fill only 8 Libraries of Congress (still not bad!).

Our busiest day was July 8 with about 240 million pieces of spam, and our slowest day was 6 with 133 million comments. Not a big range.

Overall, we missed only about 0.0206% of all spam comments this month. Although there weren’t any big fluctuations in our missed spam numbers this month, your missed spam numbers may be different. If you’re seeing more missed spam than usual come through, please do contact us and we’ll be happy to help :).

Here’s how much spam and ham came through each day of the month:


This month we did not have any service interruptions. You are welcome to follow us on Twitter or this blog for updates on that.

Here are some interesting articles on spam from around the web we liked this month:

Akismet 3.0.1 for WordPress Now Available

Extry, extry, read all about it! Version 3.0.1 of the Akismet plugin for WordPress is now available!

Even though it’s not a big round number like our 3.0 release, we’ve worked hard to make Akismet even better in 3.0.1:

  • We’ve reduced the amount of data we store in the akismet_as_submitted comment meta value for each comment.
  • Akismet no longer depends on the fsockopen PHP function.
  • jQuery is no longer required for Akismet’s frontend JavaScript.
  • We fixed a bug that was causing spam reports from outside of the dashboard (the iOS app, for example) to be ignored.
  • If an API key is suspended for any reason, comments will now all be sent to the Pending queue instead of the Spam folder.
  • …and lots of other improvements to performance and error-handling.

To upgrade, visit the Plugins or Updates page of your WordPress dashboard and follow the instructions. If you need to download the zip file directly, links to all versions are available in the WordPress plugins directory.

June Stats Roundup

This post is part of a monthly series summarizing some stats and figures from the Akismet universe. Feel free to browse all of  the posts in the series.

In June, Akismet caught 5,349,305,000 pieces of spam – that includes spam comments, forum posts, contact form submissions, etc. If each piece of spam were one meter (that’s about three feet), that would be enough spam to tour around the Earth 130 times!

Even so, the number of spam pieces caught this month is 18% less than the number caught last month. But, we caught 69% more spam pieces this month than last year in June. Here’s a breakdown of the amount of spam and ham (that is, real) messages detected by Akismet this month:

Akismet Spam and Ham Stats June 2014

As usual, there is much more spam going around than ham – there were only 2,847,015,00 non-spam messages detected by Akismet in June, which makes up just 5% of all the messages reviewed by Akismet. If each real messages were one meter, they would only be enough for 7 tours around the Earth.

This month, same as last month, there weren’t any big dips or spikes in spam numbers. The busiest day of the month was June 11th with about 201 million spam messages caught, the slowest day was June 22nd with about 144 million spam caught. In June we missed only 1 in about 2,956 spam comments.

There were no service interruptions this month, so the fluctuations of in the numbers of spam comments detected are part of spam’s natural ebb and flow. For service interruption announcements you can visit our Akismet API status page or follow us on Twitter.

The spam statistics you see on your own site may resemble those we see in aggregate, or they may have larger spikes or troughs. If you’re seeing much more spam than usual, please contact us so we can help you sort things out :).

Spam Reading We Enjoyed

  • The new Canadian anti-spam law comes into effect today, but The Montreal Gazette reports that small businesses are not yet fully ready for it, though they still have time to prepare
  • Business Insider’s Gus Lubin tells us what happens when you incorrectly click the spam button in your email inbox: marking an email as spam when it’s really not, is not cool.
  • This article from PC World reminds us that most spam comes from just a few sources (yet another example of the 80-20 rule), and the best way to thwart spam comments is by staying vigilant.

Akismet Saves Kansas City

akkcAkismet is a distributed team with members from all over the world (from Australia to Ireland to South Dakota). So, a couple of times each year, the team gets together to hang out and work on some fun projects. This past week, we all got together in Kansas City, Missouri (mainly for access to Google Fiber!). We were pleasantly surprised by how much there was to do around the city and found its midwestern charm quite lovely. The area of town we stayed in, known as ‘The Crossroads’, was full of great food and interesting sights to take in.

Heavy ReadingOnce we were finished with our projects and made sure that the world was safe from spam, we went searching for fun. We discovered that Kansas City is home to the world’s only subterranean paintball course, where an old limestone mine was converted into a colorful battleground. It was a really unique and fantastic experience – minus the bruises! Highly recommended if you ever visit.

The most visible change around here as a result of the meetup is our new and improved home page. The old version had been around for quite some time, and our designer, Dan, had a really great vision for moving it forward. Super clean, a great flow, and with some awesome custom illustrations. There is even a little easter egg for you to discover (hint: contra)!

May Stats Roundup

Welcome to the second post in a series of monthly articles summarizing some stats and figures from the Akismet universe. You can find April’s post here.

In May, Akismet caught a total of 6,562,229,410 pieces of spam – including comments, forum posts, contact form submissions, etc. To visualize this number, picture each piece of spam as a sugar cube – that’d be enough sugar cubes to fill about 6 and a fifth Olympic swimming pools.

The amount of spam we caught in May is up 4% from last month, and up 269% from May 2012. Here’s a breakdown of the spam and ham we detected each day:

Akismet Spam and Ham Stats, May 2014

There weren’t any big dips or highs during the month of May. The busiest day of the month was May 8, with just over 230 million spam messages detected. The slowest day was May 25, with ‘only’ about 178 million pieces of spam caught. You may have seen similar ups and downs in the spam activity on your own site.

We had no service interruptions this month, so any fluctuations in spam numbers we attribute to the natural way spam is posted. If you want to hear about any service interruptions you can subscribe to this blog, or follow us on Twitter.

As usual, there’s much more spam going around than real comments (which we call ham). You can see this by looking at the purple bars in the graph.

Akismet detected a total of 294,312,590 real messages in May. If each real comment were a sugar cube, they’d only enough be enough to fill about 10% of one Olympic swimming pool.

In May, we missed only about 1 in every 7,404 spam messages. If you’ve seeing lots of missed spam comments on your own site, we are happy to help with that, so feel free to contact us about it, and please include your website & your API key in your message.

Some reads from the month that we recommend:
This month, we rather enjoyed reading this piece by Adrienne LaFrance about the history of spam (going back to snail mail!), and how it affects us nowadays. We also liked Seth Godin’s sage advice (as always) on how not to spam people as a business, but still get business. In fact, in July Canada’s Anti-Spam legislation will come into effect (similar to CAN-SPAM), making the suggestions Seth Godin recommends, and even stricter rules around emailing, into law, which should make Canadians much happier with their inboxes :). We like where this is going!

A Custom Measure of Akismet Performance

Just a little something for the weekend.

Chris Hemedinger, a technical architect at SAS, recently published a great post on his personal analysis of Akismet’s effectiveness across an entire network of company blogs.

He uses his own company’s software to connect to his WordPress database and aggregate data from all Akismet-protected sites on the network. He then produces some really interesting charts and graphs for the purpose of analyzing spam activity and Akismet’s performance. Chris also makes it clear that having to manually deal with all that spam can be quite time-consuming.

And we tend to agree. 🙂

April Stats Roundup

This is the first in a series of monthly posts rounding up some basic stats and figures from the prior month. Because we thought that you may like to know how we’ve been doing and also get a better perspective of spam activity across the web.

This was a special month, as April 12 marked the 20-year anniversary of commercialized spam, which is attributed to two US immigration lawyers. Happy Birthday, I guess?

Akismet caught 6,284,116,547 pieces of spam content (comments, forum posts, contact form submissions, etc.). That’s down around 6% since last month and up around 103% over April 2013. The peak of spam activity was Tuesday April 15 (the same day that Akismet 3.0 was released, coincidentally), when our service blocked over 252 million pieces of spam content. The daily breakdown goes a little something like this:

Akismet Spam Stats, April 2014

There was a bit of an interesting lull at the end of the first week, though nothing much of note to discuss. You may have certainly noticed some corresponding trends on your own site. We experienced no downtime or service interruptions throughout the month, so any dips in the chart simply manifest lower periods of general spam activity.

We missed only about 1 in every 6,904 pieces of spam content (0.0145%).

So, what does over 6 billion pieces of spam content really look like? If you assigned each piece of spam content its own seat, you could fill nearly 125,000 Yankee Stadiums.

Some reads from the month that we recommend:
+ A reluctant ‘happy birthday’ to spam
+ The rise of bad bots
+ Zombie spam!
+ Is spam the latest weapon of the US government?
+ Spam sushi is real
