I’ve been using Mollom to block spam for a week or so now, and found it effective at reducing the amount of time I spent checking comments in moderation. In fact, I didn’t have to worry about that at all.
However, I had a report from someone whose email address the system considered suspicious (something like name@name.com), the captcha check was hard to read and the audio tool didn’t work at all.
In trying to investigate the problem I accidentally deleted about 20 recent comments. Doh!
I posted in the Mollom forums and they have acknowledged the audio issue, but gave no timeframe on a solution. So until it’s fixed I have gone back to Defensio.

Hello Michael, we’re looking into this Mollom problem and we’ll let you know when it is fixed.
