DDOSing servers fall under security, as it destroys the security and stability of the servers you use for business. Players using the cheats may not have access to P1/PS player data, but given that it takes a toll on company property and potentially damages it, it’s still a security issue.
As far as bots and wall cheats. Cheat-creating websites are running SDLC like actual companies now because it’s profitable. They already have a backlog full of ways to change their code to get around changes after a ban wave.
OW is a free game; ban waves are a joke, and they need more in-game detection of cheats to close/cancel games, then ban the users afterward. If cheat users can’t play a game, then cheats are useless. It should be an on-going fight not an every so often we do something about it update.
