I contacted Support regarding the rule of broadcasting on multiple accounts, they have confirmed that its against the Terms of Service – but when asked which section this is stated, they couldn’t answer.

So the advice is do NOT try and broadcast on 2 different accounts at the same time on Chaturbate but if you wish to have 2 accounts, have 1 for broadcasting & 1 as spare (browsing rooms & chatting as some models don’t like other models going into their rooms).
