anon and lulz are basically terrorists who ruins peoples lives for fun. They sometimes do something good, but most of the time, it's straight up crime and harassment.

Acting on your own sense of justice does no make you a modern day Robin Hood.

You mean, like when Anonymous hacked people's bank accounts and donated the money to charity? Problem is, they didn't hack Bill Gates bank account, they hacked Joe Cashier's bank account. There are some pretty bad stories that came out of that, at least one from a poor guy who had a fixed income.
