Your account was flagged due to trophies that were unobtainable in the physical version of Tom Clancy's End War. We decided to not count this game for various reasons though so you have been added back on the leaderboards now.
Yes, sorry about that. The person who removed you from the leaderboards made a mistake, he thought the platinum was always unobtainable. And I thought we cleared the bans, but appears not. Going to check and make sure no one else was banned in error for this game.
