So the result here is that of the people who actually voted, the overwhelming majority of people who saw this poll are fine with having their posts (politely) linked to/quote-posted, and a few people *really* don't want to be.
Right now there's no consistent way to indicate this preference. So you ask every time just in case, or you kind of squint and guess about when to ask, or you just go ahead without asking and ignore that there's a small segment of fedi that has a really different norm.
