There have been some big spikes in spam lately, and yesterday was the first day we processed more than 3 million comments. The spam has been coming in hard and fast, according to Six Apart’s status blog it was even the cause of Typepad downtime this morning.
Load-wise we’ve been fine, but there has been some reduced effectiveness the past week, especially with the “nonsense spam” of random characters and domains. We’ve not sure what the point of that comment spam is, but we’ve modified how Akismet learns to better deal with random nonsense content, so over the remainder of the week you should these drop off and eventually disappear, most likely around the beginning of next week.
When we do have blips, thank you being so diligent in marking things as spam, not only are you nuking things off your site you’re also protecting the entire Akismet community and helping the system learn from its mistakes. Working together is the only way we’re going to beat the spammers in the long term!
