Ask HN: Do freelancers manually scan social media for leads?

I’ve noticed many freelancers and small agencies manually search X, LinkedIn, Reddit, etc. to find people publicly posting that they need a developer, designer, or marketer. It feels inefficient and noisy. I’m exploring building a tool that automatically surfaces live hiring posts across social platforms, extracts publicly available contact information (when available), and drafts a personalized outreach email. Before building further, I’m trying to understand: Do you currently search social media for leads? How do you decide which posts are worth reaching out to? Would something like this be useful, or is manual search “good enough”? Appreciate any honest feedback.
