Good thing you learned what banevading means.
You were able to join the servers because when you restart your router, you get a new IP (Dynamic IP)
And the bans that are getting issued on your name are IP bans not SteamID bans.
Now as this isn't your fault, you will not remain banned permanently, but the ban will be lowered to a day.
Please do not join the server during those 24 hours otherwise your request will be denied.
I will issue the ban on the steamid so you won't be able to banevade.
Thank you for understanding.
