Honestly this doesn't surprise me, people seem to not understand how anti-cheat works and how intrusive it is on your computer. False bans can be triggered by a simple error when checking the hash of the file, or when the functions of a legit program (i.e Auto-Hotkey, Debugger, SDK) get flagged because of how they work. Guild Wars 2 even had a similar issue were it was proven that the anti-cheat had triggered a false positives because of an empty file which when hashed flagged up as suspicious. So people please do think that Bungie's anti-cheat is perfect because none of them are, they can all break, be broken and fooled with a little bit of tweaking with code.
