Can't see your video, only the stills. In my experience PM's are binary, either friendly attempts at humor and acknowledgement or tempertantrums that make the sender sound like a 9 year old bully. If people can't keep a civil tongue in their head than I say don't worry about the "validity" of their narcissistic complaints. Before anybody gets the keys to a plane they ought to have to read how lag and the collision model work.
