Herbert,
Off the top of my head:
What email addresses are attached to the spamming trac accounts? Is there
any pattern to them?
More importantly, are external links nofollow'd [1] to reduce spam
incentive? Doesn't appear so [2] if you view html source and search for
"reddit thread". There's a whole bunch of material when I search for "trac
nofollow", so maybe that's the answer.

I just got flagged as a spambot trying to reply to a ticket too. It did give me a captcha option though.
It's surprisingly difficult to discriminate between humans and bots; I've enabled http://trac.edgewall.org/wiki/SpamFilter and I've tried tweaking its score weightings, but it still gets some false positives, and is tends to annoy with reCaptcha interaction (and to my surprise, even spambots seem to be able to outsmart reCaptcha these days)
Does anyone here have more experience with spam-filtering who could help set up the Trac spam-filtering?
