The devs routinely break their game and aren't technically adept at it at all. That's something Blizzard could easily do but not these guys.Ah, so he can easily afford to buy a new license for the game each time he gets banned and presumably even the new motherboard didn't really come out of his pocket either then.
Meh. The devs can either keep banning him and scooping up that extra revenue each time, or figure out how to screw up his griefing. Maybe instead of banning him they can silently sabotage his account so that he's automatically visible and audible to all the other players throughout each match, or tweak his movement speed down, or otherwise kneecap him somehow so he wastes time figuring out he's being nerfed. Hell, make matchmaking take 10 minutes for him each round.
There's all sorts of stuff they could do if they really wanted to be rid of him.
Ochido is like herpes, he'll just keep coming back until DbD dies and he'll probably move on to some other niche game with poor balance and optimization.
