Continuing my long tradition (started a few hours ago) of asking "is this adequate to ban a player" I bring you this guy.  Take a look at BF4STATS.COM at his history.  http://prntscr.com/f6bplj  Sometime between 2014-09-20 and 2014-11-13 his rank was reset 17 spots.  Since then he has climbed to rank 120.  The only way that can happen that I know of is if you get Fairfight banned for a week and EA resets your stats.

He just appealed my rather old ban on him, which brought him to my attention.

Here's the page to confirm the image is genuine.  That's a great catch FroToe.  Anything that indicates that a player's profile has been reset by EA / Fair Fight is more than enough to confirm he was stat-padding or cheating.  I'm going to add in a policy that allows for any BF4Stat's history tooling clearly showing a deduction in rank to turn into a BF4DB ban.
