Text messages being prepared for a lawsuit brought by a former HBO employee show Mr Bloys wanted staff to target critics from various US outlets.
The chief executive of HBO has apologised to TV critics after a fake Twitter account was used to respond to negative reviews of shows on his television network. Casey Bloys, who is also the chief executive of the Max network, has admitted coming up with the 'dumb idea' after Rolling Stone published a story detailing a lawsuit brought against him and HBO by former employee Sully Temori.
Mr Temori has also said he left anonymous comments on some articles on the entertainment website Deadline in response to other users' negative remarks about HBO shows. He said Mr Bloys, a respected media executive who is credited for shows including The White Lotus and Succession, asked him to leave the comments.
