The reluctance to work with recruiters is mostly the "time suck" element. If you were to chase every opportunity sent by recruiters you'd waste a ton of time, but you'd also maximize your potential for getting offers that meet your criteria (whatever those criteria are).

It was meant as a statement of fact. To oversimplify, if you limit the information you are willing to receive, you won't have all the information you could have.

My main issue with the original post was that OP was crediting a policy of reduced information with doubling their salary. That just isn't the case.
