hi guys

this is exactly why I am looking for a tool that scans the messages shared with my peers. If I understood the principle of peer to peer correctly, all kind of search strings pass through my machine. If I could set up a filter for the keywords you mentioned (see gnutellameter.com: "preteen" is #18 of all searched strings!) this would be all I could do - at least such downloads couldn't be initiated thanks to my being peer.

best regards
