we chose to ban the word because they chose as a company to send people to our board to advertise disguised as regular posters. they got away with it for a while, but once we realized it, we chose to just ban the word, because if we didn't, they would just continue to do it. we have a lot of wonderful advertisers that pay megs and vlad to use their space (megs and vlad spend a lot of money keeping this place up, and advertisers help make it possible), and it's unfair to both megs and vlad and the paying advertisers to allow a company to advertise for free.
plus, it's deceptive to our posters if advertisers refuse to disclose that they are, in fact, being paid by a company instead of giving objective information about a company's services.
