You can get yourself into a lot of hot water with non correct & nasty posts personally directed at others. Its called defimation
The post in question made no reference whatsoever to a named person, named pprune user or indeed, any other reference by which a person could be identified so there was nothing "personally directed" at anyone.
It also appears that the original post mentioned has been removed from pprune so without your reply, few, if any people would have had any idea who was being discussed in the post from Aviater.
