Here's a recent example in the Russian game Escape from Tarkov[1]. A player kills a developer and gets banned moments after for cheating. Luckily he manages to catch it on video, and posts it to reddit. He's subsequently unbanned. Why was he banned? "false alarm triggered". When asked for more details, BSG responds "Sorry, can’t tell you cause it’s part of anti cheat system, hope you understand". Which is ridiculous.
BSG is in Russia and therefore untouchable, but I don't have much hope for these other companies like ATVI who are doing the sort of abuse.
