Why has Instagram blocked me?

I'm able to sign up and login, but after that, everything turns blank and I'm directed to the login page. This started happening a few hours back, I signed into both of my accounts and saw that they had both been deleted. I don't know why because I don't remember doing anything against the rules... No matter how many different kinds of email I type, my account will still get deleted and, I'm blocked. I'm very upset about this, what can I do? PS. Does me following/unfollowing & singing up/deleting my accounts all the time have something to do with this? It was a while ago... And the email address is not the same. Any help is appreciated, I role play and edit pictures so all my work is gone now...
