He got his punishment which was getting banned for scamming.there's a sentence in spanish called:
Ladrón que roba a ladrón tiene 1000 aÑos de Perdon!.
Thief that steals from a thief has a thousand years of forgiveness.
Its only cool in spanish xD
So, your saying don't scam scammers who scammed alot of people? Your saying "Oh let them be" Thats like approving of what they do. =/
Just my 2 cents.[/b]
Now if you decide to scam a scammer, it's still considered scam, of course it isnt as bad as scamming an innocent person, but scamming nonetheless.
And that saying is pure bullshit, it just incites revenge in every way imho.
