Hey there followers!
Just to let you know, I usually reply to questions on this account as private messages because I don't want to spam my followers' timelines with lots of replies.
Unfortunately, even Unlisted posts seem to appear in the Home timelines of followers, so I use Mentioned visibility instead (which is basically a DM).
Please don't think I'm being weird if I reply to you privately!
p.s. To be honest I am still having trouble nailing down how Unlisted is supposed to work. It isn't documented fully.
Unlisted is public but not visible in Federated or Local or Search.
BUT... what about Home?
I assumed it would never show up in Home unless it was boosted, but I've seen unboosted Unlisted replies to conversations I wasn't taking part in.
If someone can point to proper full documentation for Unlisted including its behaviour in Home timelines, that would be fantastic.
@feditips Unlisted is supposed to change behavior in these specific ways:
* Will not show up in local/federated timelines
* Will not show up in hashtag searches
It does not alter the behavior of posts on Home otherwise. So if you follow a person, their Unlisted posts will still show up.
I don't know where official documentation of this behavior is, however.
FediTips has moved!
