As a suggestion, another forum I frequent has an area where Mods only can post telling all users when someone has been banned, for how long for etc perhaps brief reasons (i. e. complete idiot etc). Also all threads that are removed will also state why, unless of course the original poster removed it, in which case it disappears into thin air. This is at the top of the forum listing page, so for Pprune above rumours and news, and would also allow mods to post warnings, depletion of services (no notam action available
) etc.
Just a thought to save confusion
