Reason for ban: Banned for vpn
Why unban: I was not using VPN. i was using a normal wifi and got instantly banned for vpn as soon as i joined.
I can see that you regularly use roughly the same IP. These change from time to time usually the last 2 pairs of numbers. The specific one you attempted to log into the server on ending in 71.136 is flagged as blacklisted on a few sites which is why the detection system picked you up.
A router reset should put you onto a new IP and I've gone ahead and pardoned your account.
