comment I need ideas for blocking a single malevolent user
those are all great ideas. I hadn't thought to apply some Bayesian filtering to the set. See, that's why I come to a place like this! I don't have a large enough set of known valid vs known invalid accounts to really prime the pump, but it's a start. Some of your questions: 1) I don't care if I ever make a dollar from Nigeria. If it were up to me all Nigerian ISPs would have IPs in the 666.*.*.* subnet (I know it's not possible, but should be...) 2) Not really. Mostly Mary Kay if you can believe it... 3) Hmmmm 4&5) That's another good data point, hadn't thought of that.

I had thought of that and we are also setting up a pool of known fraudulent phone numbers, but Skype can now get you a "real" number and accept SMS messages to it. If he has a seemingly infinite number of valid credit cards, I'm sure he can scam Skype just like he scams us. But I like the idea.

Right now we use a third party tool to kind of spy on what the users are doing and flags it for view if they meet any of the criteria like being from a Nigerian ip address, a new user or charging more than a small amount (our typical charge is under $100). I am sure that we are not catching all of his behavior, but the one saving grace is that we don't have thousands of legitimate users, just around a hundred or so. The site is just coming out of beta.
