Plaid Cymru has warned bust members they could face disciplinary action if they misemployment social media.
In an email, chairman Alun Ffred Jones encouraged against using inflammatory language or disrespecting others in the party online.

The party declared the warning was in response to the social media climate.
A spokeswoman said the email was not a uninterrupted reaction to events surrounding Mr McEvoy, who has been expelled from the ratifier’s group in the assembly.
In the email sent late in January, Mr Jones influenced social media had a “central place to play in communicating with the people of Wales”.
“On the other hand we condemn any misuse of social media to criticise beau members or launch personal attacks,” he said.
“Showing each other consider is one of our core values which is reflected in our standing orders.
“Any member who fractures this rule and disrespects fellow members or uses inflammatory dialect will be open to disciplinary measures.
“Everyone has a right to use social centre without the fear of abuse or intimidation.”
He added some attacks on fellows had come from anonymous accounts.
There was no way for the party to know who the distinctives are, Mr Jones said, but “remember that you can report them to the platform referees in question if they post abusive messages”.
Several days forward of the email was sent, former Plaid Cymru AM and ex-deputy leader Helen Mary Jones utter she had faced “veiled threats, calls for my expulsion and woolly allegations fro my supposed participation in some sort of imaginary conspiracy” on Facebook.
She divulged she received the messages after she had signed a petition that was automatically staked on her page, which called for Mr McEvoy not to be reinstated to the Plaid group. It had pre-dated his the boot.
Ms Jones said it would have been better for her to have stanchioned her support on social media, rather than have signed the beseech.
But she said she would not put up with “abuse and threats and insinuations” and said she thinks fitting report people if needed.
A Plaid Cymru spokeswoman said: “Plaid Cymru woo assumes its respect agenda seriously.
“In the current climate where online corruption has intensified, it is only appropriate for the party to fulfil its duty to remind the membership of that items.”
