Hopefully PCCC members are gathering screenshots (as offensive as that may be) and contacting the appropriate media representatives.
While BASSA and their members can refuse to respond to PCCC they may have a harder time ignoring SKY News, BBC, etc..
My initial thought was that this was the work of some 13 year old wanting to stir up trouble, but given the history of BASSA to publish absolutely inaccurate statements regarding other unions on their website, to publish names and personal information of individuals who disagree with their position, there may be a "there" there.
Though I still have a hard time believing anyone would be so silly as to leave such an easy trace, especially given the nature of activity.
