This kind of absurdity could happen to anybody. I was a Destiny player since Destiny 1, had absolutely no problem campaign or multiplayer. Around the time of Destiny 2 Forsaken DLC, I got bored of it and stopped playing for about a year. One day, I decided to pick it up and replay the Forsaken single player campaign "Last Call". 10 minutes in, while I was enjoying it, suddenly the game froze, and I was kicked back to the menu screen. When tried to login, it told me my account is perma banned. Shocked, my first instinct was that this is some kind of mistake on Bungie side. However, after going through the fruitless appealing process, which Bungie denied without disclosing any specificity, I believe I'm one of those falsely banned.

This is the only time I got perma banned in any game in my life. The only possible reason I can think of is that I always use some AutoHotkey scripts I wrote myself as shortcuts for Windows control, and has nothing to do with Destiny. I don't really care much about not able to play Destiny again, but because Destiny 2 had moved to Steam, even today there is still a VAC ban record in my Steam profile, which I do care about.
