yep i got suspended for a week. the reason they gave was that apparently another account i own was "permanently suspended for abuse", but i only have two active accounts and the other wasnt permanently suspended
i tried to appeal the suspension and explained that i didnt know which account they were talking about, and after a couple days i got back a generic message saying that i had repeatedly violated the twitter rules and further appeals would be ignored
iirc the only other account i have other than my public & private twitters is my old username @cutewitchyhouse which just had a tweet redirecting people to @sylviefluff, which maybe violated the rules against "username squatting"? thats all i can think of (and that account has been deleted now)
