Interesting stuff on BBc (link came from a law teacher who said it was a good summary)
"Anyone speculating today on social media about the identity of the presenter should think very, very carefully about the consequences. They could be sued for the harm they cause and financially ruined.
An innuendo can be just as catastrophic to reputation.
Ten years ago, Sally Bercow, wife of the then Speaker of the House of Commons, had to pay damages to the late Lord Robert McAlpine, a Conservative peer.
The High Court ruled that one of her tweets - which did not name the peer - had wrongly suggested he was a paedophile.
The risks don't end there, thanks to a 1986 case that leaves bona fide trained journalists with the shivers.
Back then, a newspaper reported an allegation that a detective in Banbury's CID unit had raped a woman.
It did not name the detective. But the unit only comprised 12 officers. Members of that group successfully sued, saying enough people knew who they were to assume that they might be the guilty party.
So even if a news organisation chooses not to name the presenter, they could inadvertently implicate an entirely innocent colleague."
The corporation is investigating claims a presenter paid a teenager for sexually explicit photos.
