“Its not illegal to be a "secret" member of a private group, but its a lot less legal to any pass private comments/information onto other parties without the consent of the private group members.”

Of course, yes it’s fine to be a ‘secret’ (for whatever that means) member of a private group, presumably someone invited said person into the group (see Pete Hegseth); legal to pass comments onto a third party - is far less legally clear, unless you have signed some kind of agreement not to, then it’s all fair game.

Think about the disclaimers at the bottom of many corporate emails. They will often include ‘this is confidential, if you have received it in error then you must delete and not pass it on.....’; completely legally unenforceable in most circumstances.

But what concerns me more is Richard’s claim that ‘maybe the schools have added moles into private groups’. OK fine, not illegal, but I would have hoped that schools would have more important things to spend money on, like teaching!
