I don't think that's it, Nakoichi didn't attach any qualifiers when they said we could still discuss the case. I think they just worded their post too strongly, and they appear to have used the term "Luigi posting" specifically to refer to low effort posts where people assume Luigi's guilt prematurely, not all posts related to Luigi or the Adjuster. There's a very online sort of connotation to that phrasing a lot of people didn't pick up on, and the OP really just needs more elaboration.
