Warcraft has a few stories of stupid or no context bans. Can't say for sure if they are all justified, but its clearly a system of guilty until proven innocent and getting human intervention is difficult. Seen stories on Reddit where someone has screenshots proving innocent and can't get past copy pasted or bot replies without raising a shitstorm on twitter.

Not in in tune on the activision side since I haven't played cod recently. They are 100% going to half ass the system and then fire off a bunch of human mods.
