I haven't seen that community before. Some people have way too much time on their hands to keep posting about things they dislike. But at least it proves that censorship on Lemmy is impossible, when not even us developers can do it.
I believe there is still an open issue on Github for this, but no one was interested to help implement and test it. So use the search function and contribute!
Activitypub is based on Activitystreams, and doesn't define any types of its own. Lemmy is fully compliant with the Activitypub standard as far as I know.
I agree that scaled sort is not working ideally right now. However the issues you linked were opened before the feature was released, so they are not relevant anymore. You are definitely welcome to open a new issue about improving the implementation. The scaled sort logic is here, if you have any concrete suggestions how to improve it thats even better. And I would rather improve this existing functionality to make it work as expected, before tacking on an entirely new feature which may or may not work.
Tagging would make sense to categorize posts within a single community. But you seem to suggest tags which are shared across communities. I dont really see the point of this, as communities themselves are already used for a global "tagging" of posts. So it would only duplicate that functionality.
That instance list is built completely automatically by a crawler, no one approves instances before they are listed. In this case it was removed as soon as we became aware of it. Next time please make a pull request like that one, its much more effective than complaining.
This kind of drama happens on Mastodon all the time, and within a few days everyone forgets about it. Apparently thats just how the platform works, so no need to get worried.
Very well said. Also, if these people disagree with the rules on lemmy.ml, they could create their own instance, with their own rules. Thats the whole point of federation.
Big words from someone who posts anonymously, and who never contributed anything positive to the internet.
