The writer - now known to be Richard Horton, 45, a detective constable with Lancashire Constabulary - had sought an injunction against a Times journalist from publishing his name, after he had discovered his true identity.
But in a landmark ruling, it was ruled Horton had no "reasonable expectation" to anonymity, because "blogging is essentially a public rather than private activity."
Since being exposed, a spokesperson from Lancashire Constabulary said: "He has been spoken to regarding his professional behaviour and, in line with disciplinary procedures, has been issued with a written warning."
Horton, writing today (Wednesday) in The Times, admitted he had "damaged" the reputation of his employers.
It is estimated hundreds of bloggers write rebelliously about the organisations they work for - currently protected by their anonymity. This ruling means no blogger has any right to anonymity, and can pursued by their employer.
‘Chicken Yoghurt' blogger Justin McKeating - who blogs behalf of Greenpeace against the nuclear industry, said Horton had been "hunted down for little more reason than to satisfy the personal curiosity and vanity of a journalist who clearly had nothing better to do."
‘Old Holborn", the political blogger, who praises insider bloggers such as ‘Guido Fawkes" for exposing Parliamentary corruption, added: "The British people are being slowly reduced to acquiescent slaves to work without a murmer as drones in the factories and offices of this country. If Nightjack's lucky, he might a get a book deal or a few TV appearances out of it. But his day job is most probably gone, thanks to the Times, for no reason whatsoever. I think it's one of those "Bloggers Unite!" cases."
