Hey, Mod Kelvin from Player Support here. I've had a look into your account and it appears that there's recently been some third party activity, so I've taken steps to secure it.

In order to recover your account and keep it secure in the future, please follow this link.

I can also see that you've sent us a ban appeal which is currently waiting in the queue, so one of the Player Support team will respond to this as soon as possible. :)

Hopefully this clears up any confusion regarding the ban on your account!
