Trackback Spam
Roller seems to have done a pretty good job of suppressing comment spammers. The math question seems to trip up automated scripts and I only get about 1 or 2 spam comments per month. At least, I only see 1 or 2 per month - many get marked as spam and just sit in the database - never to be displayed. However, recently I've started to notice a lot of Trackback spam.
I dive into my "comment" table a few times a week to format comments so they look like their author intended them to look (I never alter wording). In the past couple of weeks, I've noticed a buttload of spam trackbacks (up to 10-20 per day). Here is an example. How do we go about stopping trackback spam? I'm guessing the easiest way is to disable trackbacks.

I'm a fan of Bad Behavior which works for PHP and might be a model to look at for Roller. It analyzes the request and can reject it based on a wide variety of known spam patterns. When I turned off logging (which still takes a bit of database resource) it had stopped 63,000+ trackback and comment (mostly trackback) spam messages on one site alone. Because of how it works false positives are very low and can be fixed pretty easily.

Can't spammers use google to do the simple math ? :-)
