All of the examples I gave above were in the past few days.
Was he just a troubled guy who lost it? Maybe. But we do have some disruptors who literally have dozens of accounts from 1998 or 2000 or 2001 laying around aging, and when one gets banned they start using another. He may have been in that category. No real way to tell. What I do know is that people who think that way should find another online home.
Has Jim considered "aging off" old accounts so they can't be used in this way as sleeper accounts? Automatically nuke accounts after X amount of time (and X could be a year or more). IMO, anyone who selects a screen name then doesn't use it for a year or more is simply trying to place a "back door" into the system, and should be discouraged from doing so.
