Anonymous for many good reasons...
One of my websites was under constant attack from a networked photocopier/printer in Australia a few years ago. So what do you do..?
...You find the default login for the machine and set it to print 10,000 copies of a message that says 'This machine has been hacked and is being used to attack websites. Fix it. Change your login.' That's what you do.
Might have been 1,000 copies but it was enough to make 'em take notice. Never heard from that machine again.
It is reasonable to expect that if you hack into someone's system(s) then you must expect to be targeted back with a reasonable response.
