Today Akismet caught its 20 billionth spam.
That’s an average of around 10 million per day over the 5 years since Akismet first launched. Currently we deal with 30 million spam comments on a typical day, or about 350 per second.
To put that in perspective: if Akismet users had to spend one second manually deleting each of those comments, it would have taken over 600 years to moderate them all. (And each new day’s flood of spam would add another year to the queue).
How much time has Akismet saved you? :)
