weesh is right in the money, but the problem is that nowadays, ad's are contracted to ad farms, quite frequently guilty of sleazy business ways, including gain publishing and it's gator/claria adware/spyware, pieces used to install themselves without user knowledge, like virus or trojans does, and eventually bricking a computer . The legal way against those enterprises, are weak to unexisting , so It's a crime worth committing... Of course this got users quite ticked off about ad's, and we just blocked the buck out of them all. It's fault of said enterprises, or some of those enterprises, who milked the cash cow to the death, and now they complain. "We just wanted to force a thousand of adverts down user's throat. Not they blocked us, so not fair!!"*Rarity whining*
