Government computers have been used to insert insulting revisions to Wikipedia entries on the Hillsborough disaster.
Computers on Whitehall's secure intranet were used again in 2012 to change the phrase "You'll never walk alone" to "You'll never walk again" and later "You'll never w*** alone".
Logs of the IP addresses of computers used to post the revisions revealed they wee made by computers based in government departments including the Department for Culture, Media and Sport, the Treasury and the Office of the Solicitor General.

If this was one person or several, it shows very poor judgement. I would say it is a sackable offence, but if they do trace the culprit I expect it will be quietly dealt with behind closed doors. Unless someone makes a complaint to the police.
