The article's methods are actually quite good. You should ignore most of the recruiter contacts - if the recruiter approaches you for a job that is clearly not a fit for your background, I'd dismiss that person as either not respectful of your time or incompetent, and both are good reasons to ignore that person down the road.
If you're getting a fair amount of incoming traffic, you're already optimized for discovery, so that is working. Telling recruiters "I'm only looking for jobs that fit these parameters" and then paying attention to the ones that are respectful of that will work to start a relationship. I had some relationships for the entire 20 years I was in the business, and some of those people I didn't make a dime off for maybe 15 of those years.
One thing that's contradictory to what you've said that's caused me to ignore recruiters is that they misrepresent the opportunity even when the criteria doesn't match up. I've dealt with a few that I've told "this doesn't fit my criteria" and they're very insistent that the company is looking for people, not skills, and I should interview anyway. Ultimately this is a lie and I'll end up wasting everyone's time. I've done probably 30 interviews via recruiter and never landed a single position. All my positions have been the result of me just applying directly or through referrals.
Agree, but recruiters who can actually respect and match you with good criteria are valuable. I don't know why companies isn't do better job marketing / posting / community communication, but there are many jobs that feels like exclusively reserved to recruiters.
I don't think that is contradictory at all to what I wrote. I agree, many recruiters will try to send you out to every client and every job they have just to maximize their chances of a fee. Those recruiters should be avoided.
If you've gone on 30 interviews and never landed one job, that might be something you need to also consider and look inward. Going 0-for-30 is pretty unusual, unless you were accepting interviews for jobs you were clearly unqualified for.
