Lets go through some basics. Click through articles on the blog. Is there a single one you couldn't write? No, really. This is the kind of stuff you give to/get from a copywriter. Everything is formulaic, you could write the same kind of posts about literally anything. It's a craft.
Now go through related social media. New accounts posting and moding. All relatively fresh.
Obviously, I have no proof. SM part is also how you would work if you wanted to remain anonymous, sure, but how do you explain this blog? Start of the whole thing being few months after CEOs started whining about how much superior in office experience is could have common causes. And obviously every story is possible - there probably are people doing it. Did they really start that recently?
Admittedly, asking for few dollars from people to get into better parts of discord while claiming to make 6 figures doesn't match exactly. There are reasons to do that (hiding lack of content), but that generally points to creative writing and general grift at least as much.
I guess what I'm saying is wait for major newspapers to pick it up and for people who want everyone in office to use all that as talking points.
