Having an automated system for support is a massive flaw especially when your product is a live service, closing an account for toxicity is just terrible for business unless they slur, blizzard should just copy league and give accounts weekly silences and increase the time every continuous offence for generic toxicity.
Personally i got banned for literally asking for heals in an annoyed tone in 2025 in a quickplay game, asked for proof from support service, received a "we don't have proof but trust me bro you messed" type of response, haven't spent money on this game since my ban
original tweet got deleted but this is what the guy got permanently banned for. apparently they unbanned him but blizzard will continue to do this exact same thing to other people and refuse to speak out about the flaws of the system
