Will banning players result in nullified losses?

Since the division are going to be seasonal it really wont' factor into it in the long run. So I doubt they will delete the win / losses because it is exceptionally hard to prove if they have actually won the game legitimately or not. Thanks for the Question.

Seriously? Are they going to reset placement, and require placement matches in a regular basis? Is there any details on how often will this be done?
