If you get banished from Wattpad, profile deleted for breaking rules, and you try to set up another profile, the system will delete it. Once you get banished, they work to make sure you're permanently unable to be here. If you use fake info, then the account is automatically deleted.
If a book is deleted, you can not get it back up. Only can republish it, and hopefully, it isn't discovered again.
I had a Wattys submission, 1k+, and it was deleted. The reason was that two characters from America are kidnapped and held hostage by serial killers in Japan. The sex scenes were deemed as sex trafficking (cross state lines) and broke content rules.
They don't send a message/email explaining why they deleted it.
You should take a moment to read material that gets stories removed and how your account is permanently deleted. Also, a complaint/report can have a factor in deletions. Writer warnings and marked mature won't always prevent a story from being deleted either.
I stay here due to the fact that Wattpad is tougher about copywrite enforcement/infringement. If infringement, they will send a message on that and delete the story. I wrote a story based on The Crow as a homage through Hellsing characters. Once again, watty nominated and then was deleted.
