The latest update to Overwatch that's currently being tested will take a much more drastic approach to curb cheaters by not letting them play at all. In the latest Developer Update video from Blizzard, Jeff Kaplan talks about the new system they have currently running on the PTR servers that are designed to stop cheating in games, or at the very least, prevent cheaters from capitalizing on cheats. According to the video below, once the system detects a player is using some kind of cheat system, instead of simply marking that player and taking it out on their account later, the system will automatically shut the match down.
The bright side is that your SR in Competitive Mode won't be affected, but it doesn't really say whether or not the system will let you know the reason your match got shut down. But hey, I guess if the game comes to an end within the first 30 seconds and the entire team is still there on the other side, you know someone cheated. We also found out that the Summer Games are returning in August, the crew are working on a new hero that will apparently be awesome (and is a he), and a few other little tidbits about what's to come down the road in Overwatch.
