Sad story, but trueee :(
We once had a conversation about that. I see 2 solutions:
topics require 'acceptation' to be posted/visible - but why should we judge which server is worth?
create 2 subforums, like 'serious' projects and 'upcoming tragedy', by reading features (or topic owner name) we can judge if the server will be worth, more or less
But that's a forum, so ppl are allowed to post their crappy servers, so.. There is nothing you can do :P
