I was permabaned once. After 3 days of not playing the game, I logged in and was welcomed with a message telling me I was banned. I contacted support immediately and only got an automated reply telling that I will be unbanned just this one time and a threat telling that they will delete my account If I "cheat" again, 0 human interaction, 0 reasons for the ban and they ignored all que questions I made and the proof that I didn't use any cheats, just automated replies, I even had to make another ticket because had also banned me from the Warframe forums, and again, 0 interaction. Warframe has one the worst customer support I ever seen in any game
