Report Offensive Message

If you were able to actually identify and attack real genuine "hackers", legal retaliation is not really anything to worry about. Will they travel to your country to take legal action, knowing it would merely expose them to a countersuit for the initial attack? Not at all.

Should you find yourself in a position of actually identifying a real attacker, hack away. They will be able to do nothing about it. Should they try, bury them in legal costs.
