I don't think it was personal in the beginning just a user with control issues.
lol back in college some new kid banned me from my own team speak server that I transferred to a freshman because I was about graduating. I fried the TeamSpeak server remotely and DDoSed the whole network denying them any gaming server for all the games the students used to play on the LAN for a whole weekend.
I indeed had control issues.........
. I am glad I am not that guy any more.......
