More than 200 crimes across the county in the last five years have been linked to Facebook.
Rape, child abduction and robbery were just three types of offences dealt with by Derbyshire Police between January 2009 and December 2013.
Harassment charges amounted to almost half of the cases linked to the social media site, while 18 were for sexual activity with a child, four of fraud and four for attempting to pervert the course of justice.
Other charges brought against offenders included threats to kill, theft and forgery.
A Freedom of Information request which revealed the figures also showed that only three Twitter related crimes, which related to harassment, were reported to police during that time.
A spokesman for Derbyshire Police told of examples reported to police.
He said: “One of the assault crimes relates to a father who allegedly assaulted his daughter over a post he took exception to on Facebook.
“Another involves a couple who had argued due to a Facebook post. A third assault involved two friends who had been arguing over Facebook which led to a physical fight.
“The child abduction charge relates to a man who allegedly befriended a girl on Facebook and then turned up at her school and tried to entice her away.
“The man, who is 24 and from Birmingham, has been charged with two offences of grooming and attempted abduction. His case is going through the court system.”
