A developer in the US is experimenting with an app to help anti-social people avoid their friends when out and about.
Unlike the location-based app FourSquare, which enables users to see if any of their friends are nearby, the new anti-social network allows them to maintain a safe distance.
'Hell Is Other People' uses orange dots on a map to plot where friends last logged into FourSquare. Green dots show locations that have been designated as safe anti-social zones.
In a video-taped trial of the service, a user succeeded in avoiding all of his friends, but was disconcerted to find that some of the green spots were located in rivers.
Time magazine reports that it is the latest in a series of reactions against the growing intrusiveness of social media. Similar services include EnemyBook, Hatebook and Snubster.
Complaints of crimes involving Facebook and Twitter have increased 780% in four years, resulting in around 650 people being charged last year, police figures show.
The phenomenon of social networking crime was comparatively minor in 2008 with 556 reports made to police, according to the statistics released by 29 police forces in England, Scotland and Wales under the Freedom of Information Act.
But this year 4,908 offences in which the two sites were a factor were reported.
Police forces were asked to provide the number of crime reports in which either Facebook or Twitter was a key factor. This included offences committed on the sites, such as posting abusive messages, and those which were provoked by postings, including violent attacks.
A total of 653 people faced criminal charges over the allegations this year, according to the forces which responded.
Great Manchester Police charged the highest number of people, at 115.
