i think i found a way .
when i got banned in alteriwnet i got mad,
but later when i ran i4mp as adminstrator i somehow got unbanned
idk if it works for u guys but it worked for me
just simply run the game as admin (ppl that are banned and didnt run the game as admin when they got banned for the first time)
