Suppose both I and an imaginary sibling had two separate steam accounts. We both played Team Fortress 2 for some time, accumulating their own items, hats, dueling wins, etc. Thus, we are essentially two different people on steam. After some time, my imaginary brother decides to scam someone. He is marked on SteamRep as a result. A few months later, I am marked for having the same I.P. as my imaginary sibling (because we live in the same house). How would I go about proving that I am not an alternate account of my sibling's. NOTE: This is not me. While I do have a sibling on steam with a separate account, he barely uses it. He doesn't even have Team Fortress.
