How/which URL should we link to then?
My (somewhat) hot take is that large migrating subreddits should probably host their own communities, which is what we did when we told people on r/PrivacyGuides to move to Lemmy. Or at the very least, actually coordinate with instance admins beforehand about all of this, clearly lemmy.ml isn’t the ideal choice for this situation.
The only problem is that if your instance doesn’t know about that community yet, it’ll just 404, you still have to search for it first because visiting the link doesn’t make your instance fetch the community yet.
This should still be the default behavior when it autofills a community link though, I hope they make this change 👍
