Papua New Guinea's National Information Communciation and Technology Authority, or NICTA, is reminding people of the penalties they could face over offensive social media postings.
In recent newspaper public notices it has highlighted the penalties people can face if there is a complain and subsequent police investigation.
There has been criticism of new media curbs by the government but the NICTA chief executive, Charles Punaha, says the legislation establishing his agency and setting out the penalties is six years old.
He says they put out the notices after a recent flood of complaints.
"There exists in the NICTA legislation, where people who send offensive messages that are considered indecent, obscene or they make defamatory statements, the victims can make complaints to law enforcement agencies."
