I can’t recall a single time I have seen a user use “real” bullets to make a list.
That observation is across my four (very long, 80+ hour weeks) years as a co-founder and primary architect of Stack Overflow, and my three years as a co-founder Discourse looking at hundreds of communities using Markdown.
It is, at best, very rare to see a unicode bullet typed from a user.
Compare with my list observation here. I see users make that mistake almost every day!
