>I certainly dont have any CAP's saved where Q did do that, but there are a lot of Q drops to scrape through to prove one way or the other
if you're around, i went ahead and checked.
method: go to qanon.pub and hold down page end or fn+ right arrow, to load all of the posts
ctrl + f "screenshot"
you'll find that there were only (3) cases where Q posted a screenshot, with the word "screenshot" in the filename. in each case, it was the same format, never with any timestamp information.
make of that what you will, no one seems to care either way. but like you said, that's an anomaly, now confirmed.
also, if you want to see something really interesting (but maybe it's just interesting to me because i'm a nerd), there were 2 cases where an anon used that same screenshot filename format - both in the really early days. i wonder if that was Q posting as an anon..certainly some interesting posts in there, re: mike pence if you want to dig around
