Disgruntled HMV staff today staged a different kind of 'Twitter takeover' - by live-tweeting from an HR meeting where staff were being sacked.
The music and DVD chain went into administration last month, placing thousands of jobs and 230 stores at risk.
As HMV's administrators announced it was making 190 redundancies at its head office and distribution centres, its employees gave an indication of the firm's troubles by live-tweeting the 'mass execution' sackings.
A message from the @hmvtweets account on Thursday afternoon read: "We're tweeting live from HR where we're all being fired! Exciting!! #hmvXFactorFiring."
Several more messages then followed to the chain's 67,000 followers, reading: "There are over 60 of us being fired at once! Mass execution, of loyal employees who love the brand.
"Sorry we've been quiet for so long. Under contract, we've been unable to say a word, or -more importantly - tell the truth.
By this time the tweeter's superiors became aware of the rogue social media activity, and some of the messages started to disappear.
However, before they did, another official tweet read: "Just overheard our Marketing Director (he's staying, folks) ask 'How do I shut down Twitter?'"
Minutes later, they added: "@hmvtweets these accounts were set up by an intern (unpaid, technically illegal) two years ago"
Soon after the Twitter stunt, the hashtag #hmvXFactorFiring was trending on the social networking site.
It remained unclear whether the tweets were genuine or if the company's account had been hijacked, or indeed if the 'mass execution sackings' were taking place.
Administrator for Deloitte, Nick Edwards, later said: "Since our appointment as administrators over two weeks ago, we have been assessing the financial position of HMV.
"Following this review, a number of redundancies at the head office and distribution centres have been made.
"Although such decisions are always difficult, it is a necessary step in restructuring the business to enhance the prospects of securing its future as a going concern."
