DM first with money request, private key request, mnemonic request is always from scammer.

Legit person does not DM first and ask you to send money.
It does not relate to their job position, their job title, whatsoever.

Impersonators will use username, name, job title, job position to increase validity of their messages. You can protect yourself by remembering that any invitation for you but request you to send money first is scam.
