i posted before here that i used midnight since february and didnt got banned.used TP,WP and POI teleport manually and so on.i was very carefull with what i was doing.
3 days ago i was playing normal when suddenly my client dc and kicked me out of game,when tried to log in back...SURPRISE i was banned permanent. i sent ticket and got response.the action is irevocable and they wont discuss this matter anymore.
so imo hack is undetected since there is no anti-hack program.but that doesnt mean u cant get banned.even if no anti-hack program, ure logs are altereted anyways and thats what they check. i think its a lottery mostly,or maybe ure account gets flagged in their accounts list with a star,flag,name becomes red idk something when a log has been alterated when u do a server side thing like TP.its a valid point,dont u think?
anyways i bought new gw2 acc and im playing legit now.wish u all luck
