You want to keep out the bad recruiters, who won't read your FAQ. They don't even read the first line of my LinkedIn summary to find out we compete before trying to sell me their services. What might be useful is some sort of recruiter CAPTCHA that asks them questions about the position. Recruiters need you to self-qualify because naught but a handful can do that (none if your LI profile is blank). This would automate that. Keep in mind they might not have something like salary info because the hiring manager doesn't want to set a range for a high-need position. But at the same time, it would filter out shockingly high percentage of recruiters who ask for "full stack" developers and think that's the whole thing. They literally don't know that there are different stacks. One asked if I could find her any since I run a Java user group. Turns out, she needed Node.js developers. This is common. So just by asking the primary language and framework, you could filter out the ignorant ones. However, that won't stop them from messaging you in the first place
