The Game of Destruction

I use a Keylogger to make the Admin ban himself.

An Admin can't ban any Admins, including him/herself. So your plan failed. However, I unleash a virus on your computer that deleted every program on it. Including your web browser of choice and your keylogger.

I use my nuke to ruin your computer and turn it into a bunch of ashes. Ow.

I call a marsian invasion from mars attack to absorb and smoke your nuke in a pipe! 

I then nuke the marsians give the aliens Vanilla Ice Cream with Hot Fudge. The different flavors and the opposite tempatures that fast makes them blow up.

I use GLADoS to toxic-gas-spayerize your stupid ice cream!

I beat Portal in 5 seconds by using hacks.

I destroyed your hacks with my epic scripting skills.

I throw your (new) computer into a pit of water. The computer explodes. Without it you can't script, so your epic scripting power is ruined forever!

I use mah eppic lavah skillz to destroy your lavahz.

I use a pick-axe to destroy the stone that your lava makes my water. Cause Minecraft is totally right.

I am the Creeper! I ruin your pickaxe with my ability to spontaneously explode myself!

I shoot you with a gun. Not just any gun, though. A pistol.

I am Alcatraz! I make your gun explode in your hand!

I convert the prison-island of Alcatraz (off the shore of San Fransisco) into a tourist attraction. This destroys Alcatraz's reputation of a prison.
