Just don’t use a VPN when creating an account, since reddit will likely flag the account as a bot/spammer.
You can and should use a VPN normally after you’ve created the account. Might be smart to wait a week or so after making the account to start using it on your personal devices though, just to seem less suspicious. Also, make sure you have MAC address randomization and no stored cookies if using the account on the same devices that you used with your banned account.
Join the OpenRT discord server. The link can be found on their gitbook website. I believe they have some channels for Linux on the Surface 2
Edit: nvm, not sure about the surface 8, but maybe ppl there can still help
