LinkedIn's stance on bullying and harrassment
Bullying and harassment can include hurtful language which targets an individual or group of people, trolling, spreading rumours and excluding people from online communities. In the case of harassment, the behaviour is repeated and intended to cause distress. Repeated harassment should be reported to the police.
LinkedIn does not allow harassment, abuse, or sending other unwelcome communications to people. They do not permit people to use LinkedIn's services to promote or threaten violence or property damage.
