Despite it's name, the AWL is NOT a whitelist. It's called that for lack of any
better name that isn't huge.

The AWL is really a "History-based average score tracking system with automatic
whitelist and blacklist behaviors resulting from factoring past performance into
current scores".  But HBASTSAWBBRFPPICS is a rather long acronym.
