positive experience with /kbin automatically bringing in older comments and posts to newly subscribed community
If anyone votes on an old comment from the source instance, your newly subscribed kbin instance will grab the older message when the new vote comes in. Works with both Lemmy and kbin sources.
If the comment voted on is a reply to a reply, it will load in all the parent comments as well.
If you have a login on the other instance, you can vote and unvote and it will still populate your kbin comments.
So when a community isn't in kbin yet you can search @[community name]@[instance] to create it. I was asking if a similar thing is possible with threads.
