IMO Porn is a tough topic. Different countries, communities, cultures, even ISP's have different points of view & laws/regulations about it. Some ISP's stipulate in their conditions of use that porn is not allowed to be downlded (I've noticed that in some state's of USA which may or may not be related to local laws.) In some countries, it's legal to marry someone as young as 12 (I don't know about younger than that.)
But as for child porn, they are not considered to be fully mature, educated in all manners of speaking including morals/principles, etc. (They generally take their lead from adults.) But the question is who is sharing this material. Are they adults or children?!
AFAIK most western countries have in recent years been info sharing & have agreed cooperation in regards to hunting down pedophiles.
Limewire does not own or control the gnutella network. There's lots of gnutella client programs. Just look thru the forum sections for an example of some of these.
The original poster was inquiring about downlding porn & that it's become more difficult to find. It may have something to do with .wmv being filtered out. lol
There's certainly lots of porn out there. And many a porn cd/dvd ripped to share just as other videos are. Yes there's lots of rubbish out there for the smaller files. Some are excerpts, some amatuer efforts, some or many are adverts from porn sites.
Quality of Content on the Network (click on link) And no, I'm not a major porn downlder lol
But I have checked some material out.
Perhaps the original poster should apply some search terms similar to those who look for music albums to downld. Such terms as whole, complete, uncensored, AV, VCD, etc.
