Spam fighting

I used to fight spam in comments here using a simple blacklist, which contained words that only spambots used and that were hence forbidden here. That worked pretty well. Now, however, I seem to be locked in some sort of epic struggle with a spambot who posts very similar posts, but has an astonishing variety of expressions at its disposal and thus manages to slip through again and again.

First of all: Sorry it took so long, I finally put up [a PDF version of the slides][slides] of my presentation on March 27th, 2010 about my bachelor thesis. The movie in there won’t play, this being PDF and all, but it really is just the same as in [my last blog entry about this][last], minus the “real” part because that just didn’t look good enough to be projected with a huge beamer.
