They’re in the Tinder track of “X people seem interested in you, buy premium to see who they are!”
I tried it and almost all the people who had visited my profile where still hidden.
That's because they are premium members too and chose not to tell you who they were.
You need the Premium Deluxe Voyeur membership tier for that, which necessitates the Premium Confidential Partner membership tier to counteract.
It's Premiums all the way down!
They do. If there are stories of recruiters getting married to engineers who viewed their profile, I would love to hear them.
I've joked that LinkedIn is like a reverse dating site: Instead of attractive women dealing with loads of men whose messages they're uninterested in, it's men dealing with loads of attractive women whose messages they're uninterested in. :D
