Hi 

I have the same problem as pupsikkek

I have not logged into the game for a long time (about 7 months) and today I found out that my account was blocked, the reason:

This player has been banned by BF4DB and any game server protected by our anti-cheat plugin

Reason: Linked Account

But i dont think anybody played on my account becouse I don't have any progress i think and no battlereporst that somone have played in this time.
