It is a work in progress, but i think it is already pretty useful, so try the beta release and please post any feature requests or bug reports below.
So whats the purpose of "Me Human" ? One way to get banned is due to other players watching your character grind / farm for hours and report you. "Me Human" hopefully will reduce that.
How will "Me Human" do that ? "Me Human" will detect if other players are near me and if so it will react in some way. - Opening the World Map, other players should see the map animation on your character and hopefully think "Yeah no bot would open the map" - Wave / Cheer to near players, thats a risky thing if you are totally afk because if you wave / cheer an other player he maybe will react and talk to you. So at the moment only recommended if you are near the pc. - Facing other players, like if you are watching the other player.
MeHuman will deactivate itself if your character is in combat. And optional if you are in a resting area (like cities) or after reaching a maximum afk time.
Again its a work in progress, you are welcome to post feature requests and bug reports below.
