Permanent Ban

I was sitting outside of the Cygnus boss room while i was starforcing some equips and dropping some extras from my inventory. I have recently been leveling my legion with the 1-100 event (5k now wooo!), and last night used 12k Maple Points to purchase around 85 extra extreme growth potions from the event shop. I then went onto my Zero, my Wind Archer, and my Night Lord, and used the purchased extreme growth potions on them. I only returned during the current event and have been back around 2 weeks, using the item burning and hyperburn to raise my new lynn up to 260, who just completed the Easy Lucid requirement yesterday. I have fallen asleep a few times with the game still running (my char is just AFK in town) so perhaps total playtime that gave me a flag? Currently my steam is showing my playtime for the past 2 weeks to be 164.6 hours, which works out to around 11 hours a day. Obviously extremely high but I was recently disabled and have been hard grinding to build my account up. Has anyone else been recently banned? The only other thing I could think of would have been the xmas boxes, but I didnt open any extras and their post said that they had removed any in excess so I'm just really puzzled. Would my legion gains (around 2k in the past two weeks) or my game time be a reason for the ban flag?
