I (well, supposedly) knew the guy who unleashed SQL Slammer and a small group of friends (into Ragnarok Online hacking/botting) sat around on IRC watching backbone router pings go apeshit until ISPs started blocking it. It was also amusing checking firewall logs to see whose servers were vulnerable.
I have piracy accounts older than my niece and nephew.
Had to call rackspace and get new credentials for a friend in Iraq after that massive raid.
