I had the same problem myself. In fact I still run a couple of forums. And I get at least 3 "remove my links" mails per day. I guess you can't ask them money, but they already cost you money (to maintain their spam and since the panda update read their emails asking you to remove it) so I guess the best solution is just ignore those mails. Regarding anti spam I am afraid there is nothing you can do. Real humans will create an account for 0.01$ and they will post anything (I tried adding custom code in the post code as well, but those signups are not necessarily bots) In fact they even post if you don't allow them to post links (they post the urls with no http) Next solution I'll try is social integration. Maybe that would work for some time but even this way spammers will find their way to create thousands of crap accounts in FB, twitter, etc.
