Thirty-six Kent Police staff have had their knuckles wrapped for Facebook gaffes - including making "inappropriate contact" with victims of crime and making "derogatory comments and using offensive language" online.
The data from a freedom of information request reveals 55 employees were investigated for social media breaches over the last five years.
The Professional Standards Department found there were 36 "cases to answer" and two staff members ended up resigning, one of whom was a member of a Facebook group which posts discriminatory comments.
Most of the breaches were committed on Facebook with many of them relating to slagging off colleagues, the force itself, or making inappropriate contact with victims and suspected criminals.
One constable also posted a photo from an incident he attended on the social networking site.
Detective Chief Inspector Eddie Fox from Kent Police's Professional Standards Department said: "Kent Police expects a high standard of professionalism from its officers and staff, on and off duty.
"This includes behaviour online, and the force produces guidance for officers and staff on how to use social media safely and appropriately.
"Any complaints around inappropriate use of social media are thoroughly investigated by our Professional Standards Department.
"In two instances during this time an employee chose to resign from Kent Police.
"The other 34 individuals were dealt with by way of a written warning, or with the officers or staff concerned given advice by management."
The data showed Kent Police investigated the third highest reported number of suspected social media breaches across England and Wales.
The data was compiled by the Press Association and showed a total of 828 cases were reported to police bosses.
