Due to the win-trading going on currently there is a chance you will queue against win-traders. They are going to drop immediately to go re-queue against the buyers. If you see a team leave or disappear at the start, leave the game immediately. Anyone who queues against them will be flagged for permaban. Even if you didn't pay for the trade. Blizzard's automated system does not care and innocents caught in this cannot overturn bans. Be VERY careful with RBG's now. It is not worth losing everything.
