Blizzard has been trying to make sure the players of Overwatch plays a clean game since the beginning and they have made it clear that they will no hold back if a player is found to be cheating.
There is more than one way to get banned by Blizzard but the new one will include Mei’s glitch. Some players found out that if Mei activates here wall near the steps close to spawn on the small map, Mei and her teammates will be send to the top of the map.
There, they can just take down all their opponents and their opponents will not be able to do anything about it. It is not really a cheat but Blizzard has made it clear that they will take action against those using the glitch in the game.
They also added that they already have a fix ready to be released soon.
