I'd have to say be extremely careful with this. As I had never utilized this for PvP, nor for any clan related things. Essentially, anything that required leaderboards or that posted your scores to anyone ( I wasn't in a clan for this reason). And yet I was still banned.
They had released the new golem dungeon and about 1 day later I was banned. I had falled asleep with my game on, only to wake up to see "Your account has been logged into by another device, you have been logged out" followed by "you have been banned" message.
Meaning regardless if you stay away from anything related to scores and just do PvE, you can still get banned. Its rather unfortunate as I've played for like half a year without issues.
