Mods and admins can remove posts and they don’t stay on the server. If you delete it yourself, then it stays. Comments stay deleted, though and is replaced with a ‘deleted by creator’ message.

IT has a ticket in.

Exact same experience as a Mastodon user.

Lemmy.world is a server running lemmy software. It’s federated so you can subscribe to lw communities of Mastodon and comment as well. Threads and Mastodon don’t support communities though so all they can do is subscribe and comment. There is no negative to lemmy servers of Threads being federated. Threads users will subscribe to lemmy communities, but stay on Threads. If you’re on a lemmy server it doesn’t change anything. You’ll just see posts and comments with accounts ending with @threads

Because threads doesn’t have communities. All threads people can do it comment.

The thing you don’t get is that more common people will find the lemmy servers for the first time. Additionally it is more of a Twitter clone and doesn’t threaten much.

If you don’t subscribe to threads you’ll never see it.

Threads was a relatively bare-bones app when it launched. It didn’t have many of the features that users had come to expect from other social media apps, such as the ability to post photos or videos, or to add filters or stickers.
