@lazysupper @vilhelmr @scottmatter I believe hashtags work the same way all posts work: it's contingent on what your local server knows about, which is determined by the union of accounts followed by the local instance's population, and then if there are any relays being added in.
"Also, it only shows posts that are visible to your server anyway, it is not pulling posts in purely on the basis of the hashtag."

This tells me that a group bot is a more effective way of building a focused community discussion than a hashtag.
