Sidedoor lets each helper publish a private, approval-gated request link for their own network. Hunters arrive through a helper's unique link; the homepage is not a default helper profile.
Helpers create a profile, import their own LinkedIn graph, and get an opaque public request URL to share.
Hunters use that helper-specific URL to submit a LinkedIn profile. They do not browse the graph, and nothing sends automatically.
If you are a hunter, use the Sidedoor link a helper shared with you. There is no global hunter search.
