The Thai authorities have blocked a number of other news websites, notably the UK-based Daily Mail, after one article last year which included salacious details of Crown Prince Vajiralongkorn's private life. That censorship precedes last year's military coup, although it has increased since the military takeover.
The military has shown itself to be extremely sensitive to any reporting on the royal family, with both the number and harshness of convictions for lese majeste rising sharply after the coup.
