Keep getting banned for nothing

Ive had the game for a few years and Ive become a pretty active player, hitting one of top few players in certain areas. Recently Ive been getting banned on a constant basis, and each ban is about 2 months long. Each time is for an unknown reason, and its happened about 4 times now (so its been going on for 8 months). Ive heard a similar problem happening with other players, and its becoming more and more of a problem. Help
