Plutonium

In my house, my parents won't let me keep the pc to myself but at least the ban isn't permanent. Is there any way I can limit him using the pc as I am not in the house sometimes.

Thanks!

Hey. I am banned for no reason. My PC does not have any cheats but for some reason I got banned. It might have been my small brother because his account got banned(he wont tell me why but its obvious) but I am banned even though I didn't do anything. We share the same PC. Can anyone help?
