Have you checked the Dubvee ban logs? You might have been banned there years ago with even knowing it. Without even having known that instance existed. If that will make you feel any better. Happened to me. Through some weird automated ban sync process. Now I’ve learned the Dubvee admin is the tesseract dev who did all this, I didn’t even bother checking if I’m on the list. I’m feeling pretty hipster about all this.
