It is the classic spam problem -- there is no/little penalty from just shooting millions of emails out. The real cost is carried entirely by the recepient, but he has no way to out-out.
The solution is judicous fines, atleast as great as those for copyright infringement. If each recruiter was fined 100k for each email, it would quickly stop being an issue.
And frankly, if you cannot hire without these people, you need to become more involved in the local tech meetings, conferences, etc.
If you already have a job, or have no problem finding work given your experience, this is not a problem. Ignore it and move on.
If you are in that same position and are advocating change in the industry, you're trying to involve yourself in a fight that isn't your own.
People new to the field rely on these roles to get their foot in the door. Hell, I did, and I wouldn't be where I was without it. I'm not going to start a revolution against recruiters though, because I am now unable to join the fight as a professional.
If recruiters fuck you off, block them and ignore them. Don't find ways to deprive others of the same opportunity.
