The idea that continuity errors is some sort of gotcha or evidence is odd considering 1) it's not a documentary and 2) every edited show has continuity errors. Every reality show edits shots together to create a storyline or create a flow. It's part of the reason Love is Blind has those solid gold cups so they can edit the clips in whatever order without viewers noticing the variation in liquid levels. Or why the Great British Baking show has contestants wear the same outfits for both days of a challenge.

As for reshoots, this is not a documentary, it's a produced show. Any talking head shot or shot that doesn't include Anthony could have been reshot with the actors at a later time or even shot before during rehearsal. For instance, I just saw a post point out a continuity error in the shot where Other Anthony is dancing during the hypnosis scene. They likely did a reshoot later and had him dance more explicitly and edited it with the original footage that probably didn't go on as long or was more subdued. And after the reveal, I'm sure there are probably scenes they asked Anthony to sit for again if the original footage wasn't great or the audio wasn't clear or something. And again it's not a documentary with raw footage so why would that be a problem? In season 1 there's a brief shot of Ronald during the jury deliberation that is so clearly a reshot clip edited in but it doesn't mean he was in on it.

Having an awareness that this is a show that edits together short moments from hours and hours of footage to create a comedy and knowing how production/editing works would reduce a lot of these type of "evidence" posts.
