If you go into a lot of Melina's posts full of comments who didn't get the bit, it's usually because they're shitposting in the wrong subs. The Switch post was in the games comm. The fed post was in chat. DoD makes serious posts in the regular coms, and keeps the shitposting to CTH. DoD might be more subtle, but people aren't generally coming across their shitposts without some awareness of the context.
On top of that, particularly with the Switch post, their posts aren't as ridiculous as some people here seem to think. The fed post was obviously something that really happens, but ND people finding out they've spent their money wrong trying to fit in isn't uncommon, and is extremely frustrating for us - I've always masked mine pretty well, but I've seen plenty of ND kids having similar meltdowns over similar social issues. Melina included "jokes" like calling Sonic a Nintendo property, but there are a whole bunch of Sonic games on Switch so it just looks like another misunderstanding from someone who isn't particularly aware about gaming.

It's like the lib post where they just regurgitated actual lib talking points in order, like a lib who had come to the sub and decided to make a post that would completely "debunk" us. They and a few other overly online people might have convinced themselves that this would never happen irl, but a bunch of us have actually experienced their "jokes".
