Spend the next 5 years of my life learning to hack. I would go through the server's code and then go through to his network and take control over his channel. From there, someone else can carry on my story if they want to.
I'd put on a squid skin and say "this is what you get for killing my brethren" then i'd slaughter him with my axe and put his head on my mantle and go outside on occasions with it on and lead his fanbase into my lair and slaughter them manically. MUHAHAHAHAHHAHA
I would follow him too his hideout, kill him, take all his 'budder', take everything else for myself, and burn the 'budder' infront of all the fanboys screaming obscenities at me for killing Sky, and "BURN1NG 0UR PR3C105 BUDD4H!!!@!!!11!!!1ONE!!".
