EXBAcrew: The fake pccc site was established and came to public notice as it was published on the web for all to see.
The registrant of the website had chosen not to remain anonymous. That is like an author writing under his real name.
So the real name was in the public domain.
It happened to be the same name as a BASSA rep whose name was already in the public domain as he is (was?) an official of the union.
So if this information was repeated on here, it was rather like stating that Willy Walsh is CEO, as someone said earlier. It is irrelevant who further published the info as the website author had done that himself.
The person concerned 'outed' himself. (bandied himself around - to use your term)
I wouldn't be surprised if BA's legal dept were on to it before the news hit this forum.
