Mostly, I block people who come in hot and heavy over a poll about trains or oatmeal or whatever.
Sometimes I try to ask follow-on questions to let them know that it's supposed to be fun and thought-provoking.
But I realize that there are a lot of different kinds of minds on the fediverse.
I don't think I should be stigmatizing people who get upset by vague, open-ended questions, even if their first instinct is to tear into me.
