Since there are buggs that can only be resolved by a certain noobcheat program tp and stucking you at a place - i wont Name but probably everyone knows which one - i am not surprised… they probably just tp straight through coordinates since its a big time clientbased not serverbased apparently… (though was in beta… i do hope they added that one in a badlist at least… haha)
Technically it should be easier to spot the bots that way… they just have to check the movement of characters more serversided and once a character glitches/tp through the map without triggering a quest/qteleport/whatever they autoflagg it as bot - once it happens several times autoban, hardwareban and propper Investigation
