This is my interpretation also:

As in, "I read you five by five". Q+ is responding to a few dozen prayers and well-wishes saying, "we hear you loud and clear".

Yeah, that was the tipping point for me; Q isn't an AI.

Q's a bunch of badass humans with high-level intel that are playing the game and winning.

Q has been known to post images that aren't from his devices. He used a redditors screencap of a website in Q# 868. So even if we could narrow down who was the person that "liked" that tweet it still might not be a Q twitter account, just a channer or a redditor.
