I admit i used midnight way back more than a year ago. after i came back to play again because of HoT for almost 3 months now without using any third party software i was permanently banned. and the GM told me that
"we had found multiple instances where you were unlocking waypoints/POI's & skill points through teleporting directly to them. This again is a breach of the Guild Wars 2 Rules of Conduct as it provides you with an unfair advantage against other players."
where in that instance was way back 1.5 years ago... I think they are crazily banning all users who used third party software now or even before....
