Setting up a proxy like this is definitely an option I've considered. As I did, I couldn't think of a good way to limit the types of accounts that used it, or come up with an acceptable collateral I could keep from the user, that would prevent enough spammers to keep it from being blocked while being open to people who needed it.
Well, the obvious collateral is always money; and with bitcoin going mainstream, untraceable money transfers are now accessible even to nontechnical users (although I don't know Not sure if the mere act of buying bitcoins could endanger someone in certain oppressive regimes). Something like $10 is probably not a serious hurdle to anyone intent on avoiding censorship but enough to deter spammers. The money could be donated to the Tor project, or retained and returned after a certain number of edits.
Bitcoin is not untraceable.
An adversary capable enough to eavesdrop on dissidents' communication making them need Tor should be capable of tracing the publicly available bitcoin transaction logs back from the payment to the proxy owner to the originating non-anonymous financial transaction used to purchase the bitcoins.
