But I also think that whitelisting is not a good idea. There are existing many instances with only one account. E.g. mastodon.ar.al/about
We can consider other longterm solutions separate from whitelisting.
In the meantime, it might make sense to include a "more info" link in the error message about how to make a PR to whitelist an instance.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
