MomProof is not a mass outreach tool. A mass outreach tool wins by sending more; this wins by sending less, because a few dozen well-aimed conversations beat ten thousand ignored ones and the only account at real risk is one being used like a megaphone.
By default, a MomProof research consultant: a real person employed by MomProof, on the LinkedIn profile they have always had, reaching out on your behalf and in your name (anonymous if you ask). An assistant drafts their messages and they read every reply; anyone can ask for the founder directly, and a consultant never promises anything about your product. Your own LinkedIn is never connected unless you choose the own-account option.
It never touches your LinkedIn unless you ask it to, never uses a fake or rented profile, never pretends to be human when someone asks, never claims anything you did not write yourself, and never keeps asking after a no.
LinkedIn sets its own rules and they change. Nobody outside LinkedIn can guarantee an account is safe, and anyone saying otherwise is selling. What we can do is behave like a careful person and keep hard ceilings that do not move because a campaign is going well.
