Mabe said the ANC national executive committee had recently adopted a social media policy "that moves from a premise that all ANC structures and members will operate within the discipline and policies of the organisation whilst still expressly enjoying freedom of expression".
The policy prescribes that any social media posting must be legal‚ ethical and respectful at all times and prohibits members from utilising inflammatory language.
"We therefore find the recent upsurge in insults towards our leadership‚ particularly the president‚ extremely disturbing and view them in serious light. The use of social media platforms should at all times be in line with the ANC Constitution and Code of Conduct and seek to advance debates and discussions in a rational and responsible manner.
"To this end‚ we have impressed upon the Gauteng and Free State provincial executive committees to institute disciplinary processes against the instigators of disunity within the organisation‚ without delay."
