Fake job seekers are flooding US companies that are hiring for remote positions

A friend of mine was a restaurant GM a while back and showed me what his applications looked like. They primarily take applicants through Indeed, and his list was absolutely flooded with foreign names of people that live nowhere near here. In his case, it was pretty trivial to sort through because they clearly didn't live here.

Unless they've changed tactics, I think they might just blow up literally any job listing they can because the cost of not getting called back is nil anyway.

"foreign names"? Applying to a restaurant?

I should probably specify that the restaurant is in a low population area where everybody pretty much knows everyone else. And the botted applications came from people that lived nowhere near there, and were from a demographic that was all but absent from the area.

Nobody is moving across the nation to a town in the middle of nowhere to make $10/hr.

Why is he posting on indeed instead of just posting a sign in the window or just putting the word out if "everyone knows everyone"? Especially for a $10/hr restaurant job?
