Exactly. It is their job.

I'm in a freelance FB group for my country and I read there once that one freelancer has this friend who works for a company that asks them to collect a quota of emails and personal information per day. I think the range was 100-500. So what those people in there do is place a fake job listing in platforms like Upwork and tell people to send their complete and modified CV. After they gather enough from the fake job listing, the job disappears suddenly :|
