Well zap.stream is still new so it's unlikely that we would gain the attention of content owners, even so, zap.stream can be obliged to take down certain streams, there is however the option to do a "manual stream" using another provider and still interact with that stream on any of the supporting clients.

You could host your own stream like @SoccerStreamstr🏴‍☠️ or use another service like Cloudflare Stream, Mux or any other streaming provider supporting HLS stream outputs
