Maybe it could also help against vandalism if only accounts which are at least one week old are allowed.

It would be good to make an announcement one or two weeks before the event starts which asks the users from different platforms (Piefed, Mbin, Misskey, …) to test the Fedi Auth. So if issues are found there is enough time to fix them.

I think the federation was more about interacting with other instances. Like creating issues and pull-requests without needing to create a new account for every instance.

I think this would be useful, as reporting bugs on GitLabs can be annoying if you have to create an account first.

Searchengines don’t index all (of what I need) of the Fediverse and also the UI is not made to see when and where it was posted.

I just had a look at it and the English translation has a way to go until really be usable.

Whats is way more annoying though, is that they use Google Captcha of all the possibilities out there. FUCKING gCAPTCHA.
