First of all: Don't panic, you'll get your account and its stuff back.
Short story shorter, a while a go, a list of usernames and passwords appeared. The list for fairly out of date, but still it was something that was looked into. The login from germany would be a check that was ran to see if the password in the list matched the one that was currently in use. If this was the case, the account was suspended, with a message to contact support.
Your ban is set to permanent, but it is one that will be lifted when support has been contacted, to ensure that the password gets changed.
And of course... the login from germany in itself is nothing to worry about, the check was ran by me, not anyone from Germany.. besides, we all know that Germans are a friendly people who'd never break into your account
