Actually I've noticed a technique recently ... spammers copy and paste a recent forum message (from the forum they are spamming) and then add on their spam link at the end (or the middle, even). I think the rationale behind this is that, without taking much effort to understand what the forum is about, a genuine message, reproduced, will be voted as "good" by Bayesian filters, and the small percentage of spam added to the end isn't enough to trip the filter.
In fact, unless you look closely, even regular forum viewers are likely to let the message slide (and not alert the moderator) because it "looks genuine".
It's just random bits of text from elsewhere, designed to confuse spam filters, and to increase the chances of future spam getting through (particularly if your spam filter uses Bayesian inference for its algorithm - the spammer is effectively teaching your filter to be more lenient).
