I have a VPS from these deals linked to my Plex hosting TV shows that were recorded with a TV tuner and over-the-air antenna (nothing shady) -

• Hostbrr Block Storage Server (I'm guessing it's this VPS they are referring to since they lease Hetzner's IP's) - https://lowendspirit.com/discussion/6258/hostbrr-premium-storage-promo-7950xd-w-block-storage-only-7-budget-storage-from-2-8-tb/p1

Important notice about the hosting service you may be using.
We're contacting you to let you know about an upcoming action that is likely to affect your Plex Media Server setup. You're receiving this notice because the IP address associated with a Plex Media Server on your account appears to come from a service provider that hosts a significant number of Plex Media Servers that violate our Terms of Service.
Due to the large-scale violations occurring from that hosting provider, we will be taking action soon to block access and activity from Plex Media Servers hosted by that provider. We will start these blocks on Thursday, October 12, 2023.
If you leave your current installation as-is, you will have issues connecting to it from Plex apps as well as managing it. To avoid these issues, we suggest that you consider alternative hosting options, including hosting it from your home.
When moving your Plex Media Server installation, we encourage you to review our article on moving a server install to another system. These instructions will assist you with migrating the install as-is, so that you don't have to set it up from scratch.
If you do run into migration issues, please post specific details in our Plex Media Server forums.
We appreciate your understanding and we apologize for the inconvenience.
