Mollom Learns from its Mistakes

Posted by Hans de Ruiter

Several weeks ago I mentioned that spammers had found a weakness in Mollom. Well, Mollom's learning algorithm has successfully learnt the new tricks that spammers were using, and the spam comments have stopped. The number of spam attempts has not decreased, but I have now had over a week without a single spam comment coming through.

Mollom's anti-spam algorithm learnt the new behaviour fairly quickly. Within a few days, the number of spam comments that made it through dropped from over 100 down to only a few. Getting rid of the last few remaining spam comments took another few weeks. I still hope that Mollom will learn faster in future, but it's current performance is quite good.
