I love the idea presented here, where there's a low and affordable up-front fee to act as a small speedbump to anyone wishing to spam or otherwise abuse the network. They can register a thousand accounts, but it'll cost them $5000 to do it, and if they're a jerk, the accounts can be yanked. If you think you want back in on the "party" (love the name), you can still do so but it's once again going to cost you.
