I don't really care about the altcoin board, but a newbie section is supposed to help new people to learn about Bitcoin - not to exploit their little knowledge about the subject.
If this is happening in the newbie forum it is a deficiency in moderation and should be addressed. However, the notion that the gambling and altcoin forums should be deleted because certain people dislike them is more in line with nanny state thinking than the freedom based ethos of Bitcoin.
