Reply #3: Well, yes, that's one type.

There are also those that like to come up with user names that seem like babble when read left to right, but say something like imafreeper when read right to left.

Then there are those who post about a million little innocent sounding posts in different areas of DU to get the post count up. Then when they bore of the game, they decide to go down in a blaze of ignominy. LOL! Those are ALWAYS fun to watch!

There are also trolls who go right up to the line of alertable-ness but don't QUITE cross it. Alert should still be used, in my opinion, on anything alertable, they can't help but post a few alertables. Then the mods have a better idea of their pattern of behavior and can eventually present them with a concrete pizza.
