Thanks Bob, and do you know if this "possession" can be proved from possible accidental sharing or must it be found in the physical form on the persons computer, as many people in this thread have evidently accidentally come across this stuff with partial download sharing enabled and sharing their download folder before they could delete it.

I ask this because I dont remember anyone who has ever been arrested who wasnt found with this stuff on their computer (US cases as well)

This Can Be Blocked Right! Like Umm..... by File Size! Is it Possible?
Coz This Got Damn Kiddy Prns are Disguised by Other Names, Like after I Downloaded a Movie, and it's a Kiddy Prn, You Don't Even Know if it's a Kiddy Prn or the Movie you have searched and downloaded! and I think I already shared some kiddy prns, ok.... when im downloading i just leave it their whole day! and the finished downloads are shared(the disguised kiddy prns), and i noticed that the movie i just downloaded has so many uploads! after i checked it damn it's a kiddy prn!!!
Note: no worries i always delete it right away!! but so sad i already shared some unnoticed!
