I found the cause! This is terrible. It was my wedding day and I didn't write anything that day. This one was made by a friend of mine, he wanted to help me. Because I read from that date is not my handwriting, not my style. But now I know the reason of ban. That's sad. No one can be trusted in this world.  Let this be a lesson to other users, do not let anyone to their work otherwise it is easy to lose.
