its a (distributed) denial of service attack, you hear about them on the news. Its in many cases where hackers attack a company and knock them down for awhile by flooding them packets of information.
The same way some people are getting back at spammers is to ddos attack them.
Here, he got an ip addy which is essentially a porn site it sounds like. Since that IP is useless given the fact that ddos attacks usually are done by hacker obtaining control over that server at that IP it doesnt really mean a thing, that is what they call spoofing an IP to commit this attack.
I knew some people that would attack and bring down child porn sites.
Usually an attack gains access to computers via trojans or other ways to take control of it, then directs attacks to others through that system. In this case, it appears pintoca.
The most likely scenario is that this contains child porn, Pintoca's IP addy accessed it and it was recorded, a government agent or otherwise dogooder, ddos attacked all the perverts on the system that accessed that info and hence. Pintoca, was ddosed.
So, its quite elementary Dear Watson, Pintoca is Peter Townsend
