The idiot posting the weblink to a porno pic uses www.dizum.com an anonymous
server (surprise surprise). I'd suggest that you email them with the message
details (click on properties and copy/paste) at [email protected] also get in
touch with your own news provider and request that they block dizum from
posting to the Usenet.
This group has too many young kids reading it to let that one go
unchallenged.
