One thing I hafta say, when it comes to the pen, all I can think of is when P.Ryan snubbed President Trump on day 1 by refusing to accept one of the pens he was offered by President Trump (after the President had just signed his first thing). There was plenty of video of that event and it’s possible that 4chan did some screen grabbing. Also, and I heard it with my own ears while listening to Jeff Kuhner on the AM dial, a caller to the show, who claimed to be a 4channer, took credit for originating the peeing prostitutes story, on the day the “dossier” news broke. That was discussed here on FR at the time.

Looks like Ryan took one ~1:42.
It was a long post on reddit, with links to prove it. Some guy did it as a larp, and the intel people or Fusion or whoever, took it and ran with it.
The Q photos of pens were of pens on desks with writing pad or notebook or whatever it was, from close up, as someone sitting at desk or standing right next to it.
I really do not think 4chans got those photos.
I remember the 4channer making that claim. Of that, I have no idea.
