Currently, there is a list of a bunch of words like "sexcam" and
"online-casino" that are disallowed. Also disallowed are CSS tags
which can create hidden text. HTML links are disallowed, forcing wiki
syntax. Just now, I disallowed any external links which contain the
word "free", which would catch everything I've examined in the recent
batch of spam. This might cause some collateral damage, though, since
there are certainly legitimate free software websites with the word
"Free" in them.
I will add (http:\/\/.*){6}; I believe it should work in php's regex engine.
