Hi @vickieito. Thanks for the perspective/warning. While possible, I find this unlikely. If the freelancer I hired shared my info, he'd be encouraging competition and diminishing the chance of repeat business from me. I'm being contacted about the exact same service that I hired the original freelancer for.
I started getting contacted after I posted the review at the end of the gig, so I'm assuming these other contacts are reaching out to this top-reviewed lead generation freelancer's reviewers with the hope of siphoning off some business.
