In a business context verification is pretty normal…Credit Checks, Letters of Credit, Insurance Binders, Bank Statements, References, etc.

LinkedIn is a business platform. Anonymity does not seem consistent with its value as such.

Anyway, Persona is going to verify your submission against what is already in its database. Which after two decades of facial recognition and fifty years of credit reports is just about everything.

But if it matters, hire a lawyer. If it doesn’t, it doesn’t.
