Do other forums have "Gimmick Accounts" and can you explain them?

[MattSuspect]

i stopped by irc today to say hi, and a few of the guys just mentioned other message boards in passing. Other than a Knicks message board I peruse, I have never read another board. Do gimmicks exist to the extent they do here? (Ones a mod) or is this a 2+2 thing?

I once tried to explain commodus to a friend of mine, and it was near impossible, so this question may suck.
