Not from twitter, but I had an account suspended on instagram for “violating terms and conditions”. It was a business account, and same thing, I had no idea what I could have ever done to violate the terms. I appealed, it didn’t give a place to put anything, just select appeal and that was it, and they denied me. I appealed again, and it then gave me a section to write something specific, to which I requested the specifics of what terms I violated, and the second appeal was denied also and I never was given an explanation why. And when I tried anything to appeal again or message them or anything about it, it stated I was not allowed. I know this is not the same as twitter, but it’s all very frustrating how these companies can suspend an account and do whatever they want and not have to provide a single shred of a detail why, and there’s nothing you can do about it!
