I thought I’d tell you about a plugin I installed a week or so ago that has completely removed all automated comment spam from this blog.

It’s called Clickcha and what it does is present a small random clickable image with instructions on where to click such as “click the smallest number” or “click the biggest square”.

The beauty of this is only a human would know where to click. So all those spammers using tools that automatically leave spam comments on blogs are out of luck.

Interestingly, it seems that ALL comment spam has stopped. In fact, even those comments I used to get that were what I would call borderline spam have stopped too. I used to deal with those by looking at the URL, and if it was anything to do with herbal remedies or gambling etc, I’d mark it as spam and let Akismet deal with it for other blog owners.

So just stopping to think about that one for a moment, it seems to be true that there’s a lot more automated blog comment spam must be going on than you’d think.

In fact Akismet hasn’t had to deal with one item of spam since I installed Clickcha.

That’s pretty cool and is definitely a plugin worth getting.

Update: I’ve had a couple of problems getting Clickcha to work properly on another site and I had to edit the comments.php in order for it to work. I’ve also had a subscriber (hi Larry) tell me that he clicked the smallest number and it deleted his comment from this blog. I’ve also just found a load of comment spam in Akismet, so Clickcha doesn’t quite seem to be doing what it’s supposed to at the moment and I’ve now deactivated it. The concept is good though, so lets keep our eye on that one.
