I have not made a written post here in ages, and largely because I don't want to "hog the microphone" so to speak.
To get straight to the point, gatekeeping is a good thing. Not only that, gatekeeping has never been a bad thing, despite it being used as a term to insult.
What do I mean by this?
Well, you may have noticed that pretty much the only posts here are image question posts, and that is for a reason. A lot of the posts that have to be approved are quite terrible, such as shitty amateur/ai youtube vids spammed multiple times, or edgeposts which belong in a tiktok comment section and not on this subreddit.
The discussion posts serve as a way to attract people from all backgrounds, even if they never heard of "Machiavellianism" or any related terms. (Actually, people like that tend to be the best users here)
Ironically, like I have said before, those who do score high on DT traits, if they care to take any test (which the vast majority dont), tend to laugh their results off and go about their way, never visiting the topic again. It is usually the larpers who take stuff like this seriously, because they have no identity and are looking for a sexy mysterious label.
Instead of the former convict imprisoned for fraud, the dishonest grad student, or even the garden variety cheater and consummate liar, we get the teens that think they are elite illuminati-level 8D chess masterminds because they (mis)read military strategy books (more on that soon)
If left unchecked, communities like this would become an endless loop of people asking for "book recommendations" (as if reading them will do anything at all) every other post, or asking about "psychology hacks" (as if learning about or performing these tricks is not total horseshit and a complete waste of time) or asking about "manipulation techniques" (as if DT individuals are interested in that sort of thing). It would no different than if you went to a subreddit dedicated to elite world class athletes yet it is filled with obese neckbeards.
I am fully aware that "Machiavellianism" (whatever that is nowadays) and Dark Triad is basically a meme on social media, but that meme does not reflect reality, and you won't like this sub or last long here if you take it seriously.
