"Dan Shapero, LinkedIn’s Careers product lead, told me that if you turn on Open Candidates, the “looking for new work” signal will only be beamed out to recruiters who are not in any way connected to the place where you currently work. That means that even if you are looking, you won’t jeapordize your current job in the process."

How do they prevent 3rd party recruiters?

My fear exactly.

I get the impression that LinkedIn truly believes that companies will use them and them alone for recruiting.

This option will fail with really bad consequences for some job seekers.

We outsource our HR/recruiting to a few third parties in a small market (Cleveland, OH, USA), there's just no way I'd trust this. Word gets out fast enough as it is here, among other things that happen behind closed doors that I wish I could bring up publicly :(

Yes. Similar to Angel lists the default is to hide your Open to Opportunities tag to anyone from your company. I'm not sure about other companies under the same umbrella... Say you work for Youtube. Are you hidden from Google employees?
