Examples would be like the account "Godhatesfags", which most people would probably agree was probably made by a regular here.
A secondary term for Sockpuppets, though, is that they are usernames that someone will rate up so that they have rating priviledges, and then use them to mass rate down people. More than once at that.
Explanation enough?
