I understand the need to do this Skippy Jeff, but there is a much better way of doing this. It's just I haven't written the damn code yet.It is possible take people you think are scammers, SHA hash their addresses in such a way, and then delete the address/info. Then when they try to scam you again, you can hash their address and do a comparison, if you find a match then you tell them to go fuck themselves. This way scammers have to obtain numerous addresses to perpetuate scams (and I can employ fuzzy hashing to make this problematic for them unless they are ready to move to an entirely different zip code or obtain expensive services which since they are buyer scammers is highly unlikely)The power of this approach is greatly magnified if you share a black list of hashes with everybody, it should cut down on SR scammer buyers by a large factor. Even a naive implementation would deter most scammers, but we really need a clever implementation to box them in proper for good.I was working on a project to completely automate this process, so that everybody could share lists of scammers and make black lists. Because there is no actual addresses involved, this could be all public and in the open. There are a number of caveats such as a reverse address to hash attack, so there is a danger LE might be able to decode the black lists, but the idea is basically sound if I can work out a way around that attack I think.It would be good if SR vendors could use spreadsheets to keep track of data without storing address information, making interception of your accounts futile.Anyway, it is on the to-do list. I shall try and do it this weekend and then I'll hold a mini-conference on the subject for input on the consequences of its use etc.P.S. Obviously this will be open source and posted on the forums so the code is capable of being inspected by anybody.
