If this is your first ban in Rust, I'd recommend completely uninstalling the game, creating a new Steam account, and purchasing Rust again through that account.
If you aren't banned again within a day, everything is probably fine. However, if you do get banned again, you can, of course, consider replacing certain PC components or using a spoofer, though you'll still need to keep an eye on your IP address in the future.
There are also quite a few threads on this topic you can check them out here:
