If I have been "banned" is there anything I can do to get in again?

Depends how long the ban was for if its 12hours just take the ban.

Otherwise you could try going to the servers own forum to request an unban.

Thanks, is the forum locaed here or on the game/Server itself?

First of all, you should remember the server name where you were. The servers are not provided by LFS, anyoune can put a server online.

When you join a server, you should respect the server owner who is sharing his server with you for free. Usually you see some information while logging on the server. Read that information, and you may notice there may be a forum address. It is also possible that the server owner hasn't put up any forum, and you can't reach him/her.

If you remember only the server name, google it, and you may find the forum related to it if such exists.

If you don't remember which server you were, you may find the information in lfsworld.net at Online Racer Stats. Currently it displays, your last race happened at [AA]Blackwood GTi Which means the server is owned by AirAttack team. I think their forum is here: https://lx-fx.co.uk/AirAttack/forum/

You can see the server name you were most recently by going into Multiplayer/Join specific host. Host name is listed there.
