A shout-out to TypePad's comment spam filter


Goodness knows I'm no TypePad apologist: more than once I've grumbled out loud here about this or that problem.

But this morning I happened on something TypePad that's astounding and wonderful.

In the process of un-deleting a comment as spam that I'd mistakenly allocated to the trash heap (note to self: no comment management before second cup of coffee from now on), I had to go through six screens of spam like the one pictured above — all dated April 1, 2009 — before I got to the first of yesterday's comment spam.

And that was before 10 a.m. today.

Let's do the math (where's my calculator?): 6 (pages) x 20 (spam comments/page) = 120 in the first 10 hours of the day = 12/hour = 288/day.

Seeing as I'm only having maybe 4-6 a day get through now, such that I have to manually search and destroy them, that's a spam filter efficiency rate of 98%.

Very impressive.

Spam on a post talking about a spam filter. What will the spammers think of next?

Thanks for the shout-out for us. I know that some of the spammers have been on a serious uptick lately, but we're working really hard to prevent them from getting through. If any of your readers are curious how to help - just be sure that if a spam gets through, you always flag it as spam. Don't just delete it. That way our TypePad Antispam main blacklist can grow and everyone wins.
