I've no idea who it is.
Admin knows, and I trust that sooner rather than later he will get a grip on the situation. I'm not asking for special treatment, I'm not expecting to be granted immunity from criticism, and I'm not being unreasonable.
I don't object every time a post of mine gets a thumbs down, and I don't only object when it happens to me - all I ask is that if there someone believes that there is something wrong with the content of a post, and that they would have the exact same belief no matter who had written it, that they make reasoned and intelligent and mature posts countering it and explaining why they believe the content to be wrong.
But sadly we've got to the stage where they are saying that it's unacceptable for me to post my genuine experiences of certain types of distance learning systems, or that it's unacceptable for someone to explain how his training company believes that people should be genuinely competent if they are to pass C&G examinations.
We've got to the stage where they deliberately give people seeking help advice which is completely wrong just so that they can anonymously criticise my advice.
They are so far beyond reason, and so determined to indulge their stupid, petty and childish desires that they're prepared to destroy the value of this site, that the only solution is either to shut them down completely, or take away the means for them to wreak their havoc.
