Their are plenty of alternatives to cl. I personally think the way they operate is disghusting. If your not going to allow people to post then why have the categories? I'll tell you why, it's traffic, cl is so popular everyone knows of them, if they take away some categories they feel are a hassle (where they do most flagging) then they lose popularity for the other categories they consider legit. I started my own site www.duttslist.com but the problem is getting traffic so people will post.
Maybe if people would post there, browse there and just click the adds it would help with relevence and more people would know about it.
Thanks,
