I'll add my vote to the 'anti-vigilante' group.
I do not want the internet to become a free-for-all war zone, and if necessary, I will walk away rather than be reduced to the lowest common denominator.
I have every excuse I want right now to fight a hacker.
I want nothing to do with that mindset. Find another way, create a solution. Do not become part of the problem.
What next? DDoS mobs terrorizing the internet?

Nasty.
