A classic case of best intentions missing the target. Some of these programs work very well in a test setting but fail in the real world. The words describing these sites would cause many filter programs to refuse you from accessing this page if they appeared anywhere on the page and are in any case not worth repeating as I am sure you know what I am talking about. This is also one of the manifestations of the Darkside as it is called. Predators abound waiting to prey on unsuspecting victims.
Victims can be children, women and men.
Chatrooms are the favourite haunts of this despicable creature. Anyone could be a stalker, anyone could be a Victim. Never send or respond to messages that are obscene. Never send or respond to messages that make you or someone else feel threatened. Don't meet people from the Internet face to face without getting a background check first.
