Tiktok Live Farm - Streaming on several devices at the same time

I was wondering if anyone knows a strategy on how to stream on several devices at the same time. Do I need more phones or more computers? Also can I stream from one location using proxies? I've heard that people have phone farms for only fans tiktok lives but I don't really know how does it work. Is there someone who is experienced in this field and could give some tips.

Thanks for the answers
