For anyone wondering if Threads and Facebook at large will be a fine neighbor in the space and compatible with other apps/services in the fediverse: they’re already automatically hiding comments that mention Pixelfed https://mastodon.social/@dansup/112126250737482807
How do you access Mastodon content in Lemmy?
It doesn’t work so well in that direction. Lemmy doesn’t have a concept of content that isn’t posted to a community. If a Mastodon post tags a Lemmy community, it’s available as a normal Lemmy post, but otherwise it doesn’t exist.
FWIW I think this is intentional and a feature, not a bug. By spreading content to communities, you can delegate moderation responsibility much easier.
Content not posted to any community would need something akin to a site-wide moderator or an admin to moderate, and such a moderator wouldn’t be as effective. They’d cover a wider array of very different content. Community moderators work better because they can define rules that are only confined to their comm and they know better how to moderate their own community and they also care more about their own community so are more motivated to keep it well-moderated in the fashion they want.
