There really should be a feature on PPrune (like on certain other aviation BB's) whereby you can edit a post for up to an hour or so maximum. Thereafter you have "locked it in, Eddy!"
It is the measure of character (or, more accurately, a lack thereof) to say a bunch of scurrilous things, leave it out there for a few hours and then delete it, pretending to have never said it.
