Guildmate got banned mistakenly?

Thanks for the explanation
For your last point:

I understand it by “If the auto-detection thinks someone cheats, and both two reviewers also think it is cheating, then the player will get banned”. I wonder what if both anti-cheat and manual review go wrong. Otherwise, the bans will be 100% accurate

FYI, let me use @Saltypatra’s explanation in a related topic

“quite rare” = banning someone by mistake is rare, but it happens. Do I understand correctly?
