I'll get right to the point.
Ad hominem attacks are basically inevitable.
So, I'm proposing, for maybe a week, at random, all DebateArt usernames and icons be shuffled.
Of course the admins could still see the real userinfo, to mitigate potential abuse posting.
I think it would be very interesting to see how people respond differently to each other without the baggage they inevitably accumulate with familiarity.
and of course, after the wacky-week, everything posted would be re-labeled back to the actual (correct) account that created it (and not the randomized pseudonym).
