It was few years ago, they banned me for few days in WoWs. After pressing the Battle button I was crashing a lot due to windows/internet problems, my ship got stuck in battle and I wasn't able to return to it, the other players prolly reported me for being AFK too much, and on next day received a penalty with info tha that I run bot software that helps me gathering XP without actively playing.
Ofc I was not running anything illegal, it was clean windows and their client, not even mouse software installed.
Yet it was long time ago, long before the Fair Play rules and their first trike second strike idea.
