I submitted a support ticket to EA to see why I have been banned from BF4 and they have told me to try here again.
Here a link to there response: https://gyazo.com/e7ceafa64878bd78bacbc72c825ebd3f
This ban happened after 02/01/2018 so I don't know if that has something to do with it.
EA has stated that the FairFight ban was not a mistake.
While EA might only ban you temporarily, we ban you permanently.
Appeal Denied.
