It's not the miracle you seem to imagine! I deleted my linkedin account at least fifteen years ago now, disgusted by their spammy, underhanded recruitment tactics, and I have never had any trouble finding interesting work.

I understand that some people find it reassuring to receive a constant stream of recruiter inquiries, but from what I hear these messages are mostly low-effort, shotgun-blast attempts to fill undesirable positions, so I don't feel like I am missing out.
