High Levels of Spam Continue — What We’re Doing and How You Can Help

In our 2012 year in review post, we explained that, without surprise, spam levels were greatly on the rise. We are a bit beyond the halfway point of 2013 and wanted to post an update on what we’re currently seeing and to show just how true that ominous statement has turned out to be. We also wanted to share what we’re doing to combat the problem and how you can help.

How much (more) spam?

We have seen some significant year‑over‑year increases in the numbers of spam filtered by Akismet. Here is an illustration breaking down the daily averages by month for 2012 and 2013:

As you can see, successfully combatting over 100 million daily pieces of spam is the new normal. As general spam levels rise, so may the chance that some unwanted items will squeeze through our filters to hit your dashboard and comment queues. This is where we need you to ensure that you mark any such comments as spam so that they’re reported back to Akismet. This helps our software learn, evolve, and make better decisions moving forward. Because spammers evolve just as often.

What kind of spam?

All kinds, of course. But if we had to pick a winner so far in 2013, we would probably go with the compliment spammers. There are lots of variations within this category, sure, but the overall tactic remains the same. And unfortunately, we often see that folks are actually recovering comments like this from their spam folders. On this front, Mark’s post from 2007 is still very relevant and worth a read. Here are some samples of compliment spam, if you’re curious:

Very interesting… as always!

For the most part I agree with you and enjoy reading your posts.

Hi, you have a jolly good post here, thanks for the good read

[…] Check it out! While looking through the blogosphere we stumbled on an interesting post today.

What should you do?

Let Akismet work its magic and correct it only when you need to. If you do, at any given time, experience a small influx of missed spam, there’s no need to become alarmed. Take a look at the number of comments that Akismet did successfully catch during that same timeframe and examine the accuracy rate (this will help determine whether or not there is a technical problem). Then, of course, mark the comments as spam so that Akismet can process the data. Do not place the comments in the trash — if you find something incredibly out of place, please feel free to get in touch.

Finally, and most importantly, always remember that Akismet learns from user feedback via missed spam and false positive reports. This means that, when you see something that Akismet has flagged as spam, know that other bloggers have agreed with its opinion. Have you ever seen those advertisements that claim “9 out of 10 cats prefer this food!”? Well, when you notice a comment in your spam folder, think of it as “9 out of 10 bloggers say this is spam!” Don’t get fooled by the bad guys.

In the meantime, our awesome (and growing) team will continue working magic behind the scenes and ensuring that Akismet is your best weapon against spam.


  1. One thing I have done to help reduce comment spam is to only allow comments on each new post for a certain amount of time. I have it set for 2 weeks presently. But Askimet always catches and puts it in que. I have only had one false positive in the last 2 years which I quickly noticed and allowed. Better to be marked then missed.

  2. Very interesting… as always!

    BUT is the percentage spam increasing or are there just a lot more calls to Akismet?
