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.
Can you reword your second question? ‘force searching communities’ - not sure why you would want to force or automate a search.
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.
Yea that works for single posts, use the fediverse icon on the remote server for the proper url to search.
You don’t get the reply’s but you can search like that on a single reply too.
What’s the “Fediverse icon”?
For lemmy it’s the rainbow coloured hexagon on a post or comment.
