I don't agree.
Personally I'd be dissappointed if something I'd said in private ended up on a public forum whether I was attached to it or not.
Posting rumours from un-named sources is poor form every day of the week and people should be called on it.
It doesn't matter whether it is a harmful rumour or even if it's true. If you're worried about naming a source because they will be annoyed, it's probably a good indication that they never intended for the info to be aired publicly in the first place.
Looks like we're back to talking about what they print in the West then...
