>Be me, eighteen and living at home
>Pretty much a NEET, last week of school, lots of days off
>Earlier this week I notice my stepfather put on OpenDNS blocking my access to 4chan, reddit, PH, et cetera
>I shake the fact that he probably knows all the fucked up hentai I'be seen in my life, and easily bypass the block with a simple trick that involves Google translate
>I know since earlier he's literally stalin, complaining even about legal P2P and bullshit so this isn't a surprise to me
>three days ago he get tired of my bullshit and block my PC completely via the router, in the middle of a call and a game
>I get mad at first buy then I laugh at his pityful mistake and start using my phone as an external network card, tethering Internet via wifi from my phone
>today he shuts off all Internet in the house out of pure rage and annoyance

I'm in a cold war with my stepfather due to some sketchy Internet use, none of which is illegal or anything. What the fuck should I do, /adv/?
