With regard to your example 4 below, that incident concerned a particularly nasty and personal set of attacks made anonymously (probably by (a) UK person(s)) on a well-respected and liked Mudcatter of long standing. If I had been Joe, I would have deleted the posts too, done some research and posted a similar message.

With respect - the point was simply that Amos asked to see evidence of 4. Is a sensible and responsible example being to set when our volunteer police force also indulge in making abusive posts themselves and start calling other posters names?

4. No. But then, I haven't seen this happen. I'd like some specifics and some context.

This is what Joe had to say (about me) in the Guest Postings thread - I may not like what he has to say and I may be convinced that he's an idiot and a troll - The context of this thread was that a UK poster was making the point that they had been wrongly accused by Joe
in a PM of making anonymous attacks.
