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.
It never asks for your password, 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.
