Some people host their plex on a VPS (basically your portion of a server on a cloud that you can do whatever with) server and Plex recently banned a really popular one suddenly.

Some people store their plex on a vps server, and plex recently banned the cheapest super popular one because some people were selling access to Plex servers on that host.

Ooops, Plex just banned the server provider you were using, guess you’ll have to migrate it all at the drop of a hat.
