Prevalence of faking in real life?

I was talking with my girlfriend about disorder fakers recently. We’re both in our early 20s (she’s 23 and I’m 22) and we’ve both noticed fakers in our day to day lives. She’s a university student and I work at a restaurant on the same campus.

Both of my parents (49 and 50) as well as her father (60s) know of the faking phenomenon. I’ve seen posts on teaching subreddits from exasperated teachers. My brother (13) had brought up a few mental illness fakers in his middle school classes. It seems to be a common thing, but I’m curious just how common it really is.

Have you guys seen/interacted with any fakers in your day to day lives? Being on a university campus 5 days a week has shown me how much it’s infiltrated literally everything. My girlfriend was in a club that had ≈75 members, 5 of which were “DID systems”, and almost everyone said they were autistic.

If you have any stories I’d love to hear them! Faking has clearly gone mainstream, and it’s sad. By the way, sorry for any formatting issues, I’m on mobile! :)
