Many users wish to see something done about this. The one thing that cannot be done is for limewire to put a trace on these people. Limewire only makes the application and the users are the ones who are in a position to do something
The subject has been discussed many times and this is one of many threads
http://www.gnutellaforums.com/showth...ht=kiddie+pr0n
Also search (above right) for Kiddie Porn, or Child Porn
These threads contain, I seem to remember the place in the USA to report these criminals, and in other countries the police are the best place to start.
Just remember that a recent case concerned Pete Townshend, who afaik was totally innocent of any wrong doing, but was caught with child porn on his computer, and got into a lot of trouble over it. So Do be careful. For my part I have to come across any of this filth ..
