Strict action is being taken by Overwatch’s developer, Blizzard against the cheaters in Overwatch. According to a recent post from the official forums, any players found using hacks, bots or third-party software will be permanently banned on their first offense, no warnings given.

While we are unlikely to publicly acknowledge when accounts are closed as a result of cheating or using unauthorized programs, we have and will continue to monitor Overwatch for exploitative behavior, as well as take action as needed to preserve the integrity of game.
