I had a vip ban from awhile ago. I was playing 2 weeks ago and it worked. I also there's nothing on bans.wonderland.tf about it either.I think (I'm not sure) that your privileges were terminated for repetitive rule-breaking.
As said, I'm not sure, you should ask the Head Administrator or the Owner
Anyways here are the rules:
Read Me - Donator rules
All the general rules apply to you, however, these rules are for all players with donor privileges. You are not an admin, do not take it upon yourself to decide if something is against the rules. If it is unclear or open to interpretation, then do not initiate votes. Do not use your perks to...wonderland.tf
Im not on right now to check IP. It was on the NY jailbreak tho.I checked SourceBans, and you should still have VIP+. What is the IP of the server that !vipmenu isn't working on for you?
