Bitcointalk's indifference towards alt coins only changes to disdain when it interferes with Bitcoin discussion, which is why it was given its own section. Removing the Alt Section would just lead to people posting about alt coins in Bitcoin related boards, which would be even more annoying.
Which is also why lots of subforums we don't necessarily want, are required. Trying to stop the bath running by closing the bathroom door does not work, its simply going to floor the rest of your house.
Right, I spent months fighting for the Alt subsections that exist today. Creating a vetting system for coins on an individual basis would interfere with the indifference that we have worked so hard to build

But seriously, people are way better off with their own forums. Then you don't have to deal with someone else's rules. We don't have the resources nor desire to cater to the Alt Coin communities. Bitcointalk offers a basic board for people to make their announcement, find their community members, and then migrate to a place where they can discuss uninterrupted by others.
