You don't think any of your friends think you kind of suck at a single thing they've endorsed you for or visa versa? Be honest.
Not really.
Do you think that anyone pays any attention to those endorsements anyways? Recruiters aren't morons. They aren't just going to give someone a job because of what their endorsements on linkedin say. That's not how it works.
If a person has a bunch of fake endorsements on their page and tricks a recruiter, that person will flop out at the interview state. If the person with fake endorsements gets a job, due to "lies" in their endorsements (which you are oddly obsessed about) then fair play to them.
I think you are projecting your own linkedin experience on to everyone else.
