Because the forum needs money from the majority of people who can't do basic programming to avoid those ads.
You can inspect it, and see what's up. (Because I won't tell you.) I keep my AdBlocker off on BCT, though. The ads are fairly non-intrusive and are only fillers between posts, so what's the big problem?
I have an ad blocker activated even on bitcointalk but I still see those ads. I'm not angry at all ! My question is: how do they do that ? How can they bypass adblockers ?
