Medium.com sites everywhere with different domains?

[APCarr]

Question - why does there seem to be so many different websites, which all seem to be part of medium.com?

Time after time I'll click a link to some article, realize I'm on Medium... but it's a different domain? Yet it looks exactly the same, and I'm already logged in?

Is is some kind of spam marketing, or a look-alike platform, or...?

This is part of the medium business model, if you pay a monthly fee, you can run medium in your own subdomain, as a blogging hosting platform.

This way your readers won't get the whole content blocked with a message and asking for a $5 usd a month subscription.

The content is now getting blocked via a popup not only by following links via the medium newsletter, this is happening in organic search results from google directly.
