You're lucky. I got so many junk job offers over the years, mostly secretive "amazing opportunities" they would only talk about over the phone.
I one (rare) time replied that I receive several such messages per week and that if recruiters want our attention, maybe they should reveal more about the offer (sometimes they reveal literally __nothing__, not the industry, not the tech stack, nothing).
The recruiter got extremely offended and said I was rude and that I just missed out on a great opportunity.

I set it to "Open to Finding New Jobs", and then get 1 to 2 applications per week. I found my last two jobs by recruiters contacting me.
It works great for that. I never had any use for all the social networking.
