"Q3 would the moderator bar the individual that
submitted the photo: for not having submitted the picture
via the moderator. "
No.
But I'd delete the photograph if the a/c reg or some other distinctive feature enabled the helicopter or the pilot to be identified. And I'd ask the individual not to do it again.
Because -
(1) I know the CAA monitor the forums (and don't doubt some contributors work for the CAA) and I accept the CAA Enforcement Branch have their job to do, but I don't like the thought of PPRuNe being responsible for a pilot being prosecuted.
(2) Although Vfrpilotpb seems like a thoroughly sensible chap who wouldn't complain or criticise unnecessarily, this is an anonymous forum and I wouldn't want the 'anti-helicopter' crowd using it to cause trouble for a pilot.
(3) It's not fair to allow people who (effectively) have no means of obtaining redress to be criticised on a public forum.
