To get around the problems mentioned by D_K, the mod could design some penalties for posting in one's 'normal' style. I have an idea in mind, but saying what it is would spoil it.
Isaac would have to learn how to be pithy, for starters.

There are lots of ways that this could work. My first thought would be a Shakespeare-themed game with a strict format requirement for posting, like say, ten lines in iambic pentameter.
Mafia Idea: Pre-made Screen Names?
