I have noticed that the "contributes to the community" accolade disappears whenever it wants to.
The hubberscore, I STILL don't know
it may be a combination of hubs, comments, questions, answers, forum posts, feedback...
It seems really weird and unpredictable
My score went up 5 point in 2 days, and I'm fairly sure it will drop a lot soon.
Also, the accolade I mentioned earlier, keeps doing disappearing acts
