Mastodon has a verification mechanism, though it looks different from Twitter's. We do not ask for your documents. Instead, if you have a website that you are known by, you can verify that you are the owner of that website.
Link to your Mastodon profile from the website, either through a visible link, or through a <link> tag in the head of the document, with a rel=me attribute, and link back to that page from your Mastodon profile. It should then get a green checkmark, like @Mastodon.
Per profile page, you could say.
It works by crosslinking: your mastodon profile page contains a tag like <link rel="me" href="https://mywebpage.example/aboutme"/>. Your aboutme page needs to link back, e.g. <a rel="me" href="https://mastodon.instance/@myusername">Mein Mastodon-Profil</a>.
This crosslinking can be checked automatically, and the instance of the viewer does exactly that.
@anathem but is this only on mastodon.social or across federated nodes?
Can i validate people on my node or do they go through this process?
