QA regards to Linux and possible account issues

Hello, due to i have a few computers and my room mate has a pc that cant upgrade to w11 and the pc works perfectly fine and no need to upgrade. We plan to move over to linux before w10 support ends, but I have seen/read there have been issues where people have been accidentally banned and it is possibly quite a lot of work to get in contact if your account gets banned etc to appeal it or just get auto answers. What reprocusions can be done or try to prevent these issues occurs and basically make a mess for our accounts to avoid this will happen?
