I have gotten so many fake recruiter contacts, it's not funny. At this point I don't know who is real and who is fake. I talked to real recruiters at Big Tech companies and they said their entire profiles have been fraudulently copied to steal candidate information or to get them to pay to get "favorable attention" during the interview process.

LinkedIn is doing nothing to stop the fraud at this point. There's almost no way to tell if you're talking to a real person unless you meet with them personally at their office.
