Hello,
I've just checked the ban logs and there are no bans attached to your account. I believe you might be using a VPN or playing on the server from an Internet Cafe.
The ban was issued on the 22nd September 2021, whereas you only joined the server a week ago. If you're using a VPN or playing at an internet cafe you run the risk of being caught up in a ban even if you're an innocent player.
I can currently see you're on the server, so you're not banned.
Appeal accepted/denied I guess?
