Handling trolls with multiple accounts over VPNs

[codinghorror (Jeff Atwood)]

At any rate, after some discussion internally, this isn’t something we (CDCK) are going to be able to work on any time soon (many irons in the fire and all that), however a plugin from one or more community members (either written by or sponsored by) would, I’m sure, be appreciated by many. Or at least that subset of site owners plagued by slightly-smarter-than-the-average-bear trolls, anyway.
