If you have problems of this nature, I suggest the following:
File a helpspot ticket, and work with Customer Service. They have access to player accounts and can do an investigation on the situation.

There are some simple ways to prevent "Hacking" and they jive with the TOS.
- Don't account share.
- Don't give away your passwords.
- Don't bot.

Another helpful thing is to ensure that you are not using the same password on multiple sites, and that the password you are using is not weak.
