If I was to buy a subscription to an IPTV service & configured a Plex channel on my Plex Server to connect to the service - I would then be watching from multiple devices around my home. Perhaps multiple family members would be streaming at the same time.
What I am wondering is, because there's a possibility multiple clients would be streaming channels - BUT via the 1 server, would this be considered abusing the service?
I don't want to go ahead and pay for a subscription if after a few days/weeks I get my account suspended for inadvertently abusing the service.
It wouldn't work. The stream would stop when you started another. Unless you got a service that allowed multiple devices to use it at once.
