I personally don't think there's enough evidence here to say he was trying to grief you. If he actually rams you in the future or actually griefs, let us know! Not issuing any punish points at this time.
Issued three punish points, which became a perm ban.
However in that third clip you have no flags to spawn on, technically those two kills were legal lol.
Looks like you cheated/were banned originally in BF3 and the ban transferred over to BF4.

You'd have to appeal with them.
You had a 1 day temp ban for team killing
