What do you think about paying to hackers for destroying porno-sites?

I think it is the real way to defend our children from porno-industry. Some years back in Italy the Catholic radio station "Ave Maria" used this way to fight with pornography. There were many porno-sites destroyed. But after some months that struggle stop.
Now here is one interesting site http://www.hackersagainstporno.f2s.com It's an organization that pays to hackers from donations.
