If you believe you have been unfairly banned, you can try appealing to the developer for a ban lift. You will be barred from the servers if you have accounts with a VAC or game ban in any game (including Rust) that are less than 180 days old. Accounts linked to multiple game bans will be permanently banned. You can appeal a community or modded server ban by reaching out to the group that banned you. You can also use a bypass game bans. Depending on the server, there may be a specific ban appeal process, or the server may independently review the ban and decide whether to lift it or not.
