Uff many Q
Yes i pay 1 active sup and modify that version for my own needs.
No teleport since its easy detectable and not needed with mounts its acrualy loosing time because of crashes and desyncs. Its a farm bot gather kill do events sell at tp. No pvp or wvw
They kind of do but they dont ban you without double check. They mostly got a server sided finger print which u avoid by randomizing routes skills movement. And player reports.
I dont think that you can actualy detect good setted up bots that are not running pvp or events 24/7. My bots vary each between around 50 different spots with random route and time of farming each. Also have some offtime / afk time.
