It's strictly enforced on the anime related boards moreso than others..

First, you must answer these question?

What purpose does an avatar serve that a tripcode doesn't?

Why do you think this is place for it rather than going to a site with avatars?

An avatar is just a cool image representing a poster. Idk why forbid it.

Avatars contribute to the image limit of a thread while tripcodes do not. That's the only real thing against it.
