@mryusuf115 no, there are no ban appeals. You gotta read up on the anti-cheat, it specifically says in BIG RED BOX that you can't do that... you have to be in LAN mode... SOLO mode will still ban you.
should be 7 days (unless you tried to bypass the ban, then it would be 14)
just gotta wait it out and review the rules!
