I notice how certain content or phrasing acts as shibboleths for affinity groups, with your reaction to the stimulus itself being the gatekeeping test by proxy. Like, if you take the bait, I know you’re a tourist, because regulars know that it’s bait for newbies. There are interesting interactions at play between insiders in these threads, as many normal users seem unable to understand that they’re interacting with promotional content, regardless of whether there’s a real person on the other end.
