Yes and no. If one person posted a bunch of this stuff in one spot, that would be satire, and the ironic contrast between text and intent would be heightened. But having a lot of people do it diminishes the contrast. Here the mass behavior weakens any satire.

SNL can pull off a loud and obnoxious Trump character, because they show they can work in many other registers. But SNL itself doesn't become indiscriminately loud and obnoxious throughout a whole episode in hopes that people will make some meta-level connection between general obnoxiousness and Trump. And for good reason; a tiresome character in contrast to non-tiresome characters can be good drama. A tiresome show is for most poeple just a tiresome show. There's a reason badfilm like The Room is very much a niche taste.
