It takes a long time to have your account fall off of probation, and they won't reveal how long it takes. You need to improve your behavior on the whole, for the long run, and not just try to cheese out being a little angel for a few months. Be on your best behavior, and make that behavior a permanent way you act in the game. For a while, I would recommend muting other players in the game, as well as shutting off AllChat so you don't get triggered by other people. Just keep your thoughts outside of the game (scream them into your computer room, a pillow, into your friend's ear on Discord, whatever) and you should be ok.
