you can follow pixelfed accounts from other fediverse issues with mostly not problems, you can comment and see comments from any service in the fediverse. That is: fediverse integration works as intended.
But Pixelfed is a social picture sharing application. You can follow a mastodon account, but pixelfed will only show you the media posts from the user, not the text ones (unless they’re comments on a picture) for instance. As some other features mastodon posts have that pixelfed ones don’t will not also work.
Conversely, you can follow a pixelfed account from mastodon, but most mastodon implementations don’t support picture albums of over 4 pictures, you will not see over 4 pictures on the post.
That is working as intended though, they’re different apps with different features, just talking the same language.
Do you mean a bot that posts news automatically from an RSS feed? Because both of us are using software for post to lemmy right now.
