Tumblr account terminated?

That's strange. Sorry I'm only just seeing this now! Did আপনি ever find out what caused this to happen?

One possibility, I suppose, is that আপনি might have the same external IP address as a tumblr user who got banned for life. Even though external IP addresses are supposed to be unique, there's really only so many of them and sometimes freak things like that happen. However, they also change from time to time. আপনি might find (if আপনি haven't already) that if আপনি try to create an account again, আপনি will have no problems.

(BTW I've apparently shared external IP addresses with people from জাপান and New Zealand before. I live in England.)

It could have been something else of course, but like I said, it's worth trying again if আপনি haven't yet. Whatever it was, it could have easily just been an in-the-moment freak thing that will never happen again.
