Lurker here. You evidently believe that the posts that Q responds to are Qposts themselves. Perhaps try to understand the nature and make-up of the chans before decrying the info contained therein. You seem to lack an understanding of the basics in said anonymous forums. My 2 cents.
In the first example, Q responded to his own post using a new trip code...it was early days and a bit of slight of hand was needed as the hoaxsters realized they were being too specific.
But even if I'm wrong, the message Q posted in response is completely false and none of it ever happened.
These early Q fails are conveniently papered over to the point of being forgotten.
The second example occurred during the recent hacker attack on Qanon...after which there were numerous Q posts made which were not valid Q posts.
This post was not a response to anyone and its relevance as a valid Q post has meaning to anyone playing the game.
-btw it IS a valid Q post...for the folks playing at home who may have misplaced their decoder rings.
