Paid subs are normally locked to the amount of streams they allow some allow 2 streams at the same time and some only allow one but you can purchase multroom connections.
Also I'm not entirely sure how some are claiming they can record and view another on a single connection sub it could be that the server doesn't automatically boot one connection when another is connected FYI if that is the case and the server finds out your abusing it then they can bann you or they are just resellers that don't know that they are actually selling multiroom subs.
Ps mods I've just re read this post and I'm not sure if it's borderline to braking forum rules if it is feel free to delete it and apologies in advance
