The new forum does have a lot of spam from people trying to reach 50 posts, I agree, but in a sense, I think that's better than the btkoin and virwex and bitcointalks spam because at least the people trying to get to 50 posts aren't scamming people out of their money. So it's definitely a step in the right direction, though I don't think it would hurt to put a limit on how many times new members can post in an hour or something.
