In group of humans, there will be a signifigant number of idiots. EoFF is no exception. So what happens is that with every batch of newbies, there are smart people who don't draw too much attention to themselves, and idiots who do. The idiots, being idiots, get banned fairly quickly, hence the skewed perspective you seem to have on newbies. With the exception of those who join purely to advertise, first-week bannings are comparitivly rare.

That, or they're second accounts.
