The Deborah Koons avatar was created as a joke punishment. We had a user who posted like 40 messages just to bump his post count so his avatar would change. We thought it would be funny to punish the user by assigning him an avatar that nobody in their right mind would want. Hence, it's "punishment". It's a temporary thing though. We'll set it back. But! let this be a warning to everyone--frivolous posting will get you this "scarlet letter". :)
We had thought to use MG, but we ran out of levels.
