I am fairly new to Limewire and I understand that there is no way you can be made responsible for the contents of people's harddrives, nevertheless, I think that you are a fairly large and important entity in the Internet community, and as such there is a social responsibility that can't be ignored. Like I said, I am new to the program ( a couple months) and I am already aware of the incredible amount of underage and child pornography that is easily obtainable through P2P- Can you please supply us with a list of sites where these IP addresses can be reported? I live outside of the US, so calling the FBI is not exactly an option for me, and I really don't know how seriously these claims would be taken in my country. On the other hand, I think that just as you have moderators for the forums to check for bad language and other innapropriate things you could have people who "moderate" or constantly check for the contents being shared through your system. I am aware that the amount of material is huge, but it is worth the try don't you think??
In the same way, users could perform these searches and report the IP addresses, but in order to be sure you'd have to download the content, and this is stuff that I don't believe any "normal" person would want to see, and there is also the fear of being prosecuted for downloading such material.
I'm just making a few suggestions here, since I am one of the users who have come across this kind of material. There has to be something that can be done, and again I would like to emphasize the fact that you as a company, and us as users, DO HAVE a social resposibility to try and stop this disgusting and damaging material.
