"when the ip of your equipment changes
wants to enter they block you"

It is not true. Facebook does not block the account or user just because they access an account in different geographical locations. It does not make any sense.
Anyone can access their social media accounts from anywhere in the world.
They may just ask you to login in again and enter the password again. Possibly verify via phone or second email.

We are an abuse fighting project. Your account was reported for art plagiarism. You need to verify via Facebook account to confirm that you are the author of the art that you post.

Thank you.
