There goes season rewards for, well, a lot of people.

"We are still working on the details for the 2015 Season, but the current plan is that players who have been Chat Restricted, Ranked Restricted or Game Banned during the 2015 Season will not receive Season Rewards in Ranked. Players who have had Low Priority Queues won't be affected unless they have had 20 min Low Priority Queues. Emails and Player Support sites will be updated with this new info when we finalize the details."

I guess my 1 (ONE) game chat restriction on my other account is as bad as elo boosting.
