Well. You are right. Nobody needs to download it. But the problem is, that those files are not only have lolita, etc. keywords in their files, but also "common" adult-related keywords so if you are searching for "usual" adult-files you also get those files unwanted.
@Moak
It seems we have the same thoughts about that stuff. But how can anyone really think trading kiddie-porn can be legal?
Here at germany you can get to jail even if you have pix, etc. UNWANTED by the gnutella-network. Of course noone can get rid of those files (a helpless hope), but the problem is that even "normal" guys like me will have to defend themselves because of unwanted files on my harddisk. (even if deleted it's easy to recover)
And I just wait until a tv-magazine will hear about gnutella and those files. Just a matter of time until they tell at tv all gnutella users are pedo. Just like they always try to tell the viewers that 1st. person shooter will take us all to killers.
