Yeah I don’t agree you can make or should attempt to have a universal policy to follow in your interactions with others. The situation matters , the relationship to the person matters. Those two variables can branch off to policies. Interacting with any stranger in real life for example - What about the cost benefit analysis of these interactions. Benefit - in my entire life I can say I never received any longstanding benefit. Costs - throughout my life I have incurred an incredible amount of trouble and problems from interacting with strangers when I have not instigated the interaction. Therefore you should assume bad faith even danger and not interact going forward for all strangers that approach you.
