There is no stronger signal that you're a good developer than already having a job at a company that has stringent hiring standards.
I get multiple serious recruiter contacts a week. Mostly via Linkedin, but also via direct email for the enterprising recruiters. All from companies most people would kill to work for. I even get linked-in email from linkedin recruiters.
I ignore most of them. They know it's part of the game. One day in the future I may need them, and there's no point in pissing them off - they're only doing what they can. You gotta have a huge funnel to hire even 1 person (it's probably 1000:1 for contacts/hire)
