The comment (https://github.com/tootsuite/mastodon/issues/5463#issuecomment-530717268) is:
" @Gargron I understand your use case scenario in this, but... when people use hashtags in a unlisted toot, they explicitly want to include this toot to a hashtag timeline. I know that there is a warning, but that doesn't make it less confusing. To be clear, I'm not talking about replies, cause when they will appear on hashtag timelines they will be out of context.
It is especially confusing, because the hashtag in a unlisted toot is clickable. A user will expect when they click on that hashtag that their unlisted toot will be visible on that hashtag timeline. If not, they will probably think there's something wrong.
So there are 3 options:
1. unlink hashtags in unlisted toots.
2. show unlisted toots with hashtags on hashtag timelines.
3. make it an user option to show unlisted toots with hashtags on hashtag timelines, where the current behaviour is the default. [this is my preference]"
Let's have a little #poll. What do you prefer?
[ ] Option 1
[ ] Option 2
[ ] Option 3
