I highly recommend minFraud from MaxMind. Very, VERY inexpensive
($0.004/query), very reliable, and easy to integrate. They already
maintain a list of proxies, TOR exits, etc, saving you the time of doing
the work yourself. Can you do it and keep it updated for $0.004 per
transaction? I can't.

You could start looking at the User Agent used by each new account. If
the browser string is exactly the same, you may have yourself another way
to detect.
