tl;dr: When asking strangers for help, put yourself in their mind: establish credibility (ideally through proof of work rather than institutional affiliation), provide concise context that connects to their interests, and make the request specific, bounded, and low-friction. Critically, make it easy to say no—a pressured yes poisons the relationship, while help freely given builds one. And never lie, since any whiff of dishonesty kills the request.
