I have noticed that Headhunters who operate in a particular space in Capital Markets or have a job opening in a certain area will create LinkedIn groups for the sole purpose of identifying candidates. I never join groups that have been created by a headhunter unless they are personally recommended to me.
For me, LinkedIn is becoming a bit like the Wild West, and its usefulness will be diluted by recruiters who misuse the service.
