Is there anyway if being able to use my computer for roblox again?

Recently i got termnated on my computer over a false ban and stuff, i have a couple posts about it here i wont get into detail unless asked. Is there anyway to make my computer useable for roblox again? Ik theres a HUGE chance my computer is completely blacklisted from my termnation and i dont want to risk my real alt getting termnated, but i really hate using my phone and dont have money to get new parts or a new computer. I dont really know if vpns will work either, or stright up moving- since i do plan on moving out eventually... but It really sucks atm becuase roblox keeps denying my appeals and wont even read them and i just wanna play on my computer. I dont think my wifi is banned since i can play on my phone with wifi but they already banned my brothers account for simply having the same 4 numbers and me signing in on his computer befire in the past.
