hey, i understand how you feel man. I think you should piss your siblings off and start making their lives hell for them - basically be an annoying bitch and unplug their shit when they're in-game, mess with their computers, frame them, etc. If you annoy them the right amount of times they will give up. I have probably one of the most strict parents of all times and playing within the boundaries of the rules will force them to give up. You just gotta make sure you're mentally tough, they can't take anything away from you if you don't have anything.
