London: A British man has developed what he claims is the world`s first bullying alert system for social networking site `Facebook`, which scans text and flags up abusive behaviour.
The father-of-four Paddy Clarke`s software scans walls and inboxes for trigger words and phrases such as "gay" and "fat" and alerts parents when they appear -- he came up with the idea after reading a string of cyber-bullying horror stories, the `Daily Mail` reported.
Clarke said he hoped his system, called "Know Diss", will keep children safe from online bullies. "Cyber-bullying is very topical at the moment, but this software is the only one in the world to search through text on social networking sites to protect children.
"Know Diss is a very simple concept. It is also a partnership between parent and child because one cannot sign up without the other," the 48-year-old said.
Clarke, a consultant in pain relief at Gloucestershire Royal Hospital in Gloucester, joined forces with friend Alan Saul to design and implement Know Diss, which costs 12 pounds for a yearly subscription.
Together they trawled through sites such as Urban Dictionary and watched the television series Skins to build their comprehensive database of insults.
