No JavaScript code will (or should not) work on Chaturbate for these exact reasons but what I have seen some rooms do (or have done) is overlay the entire page with a background colour with a very low transparency so it looks "normal", set it to have a pointer event so it can not easily be selected, then add a z-index so it is on top of everything, meaning you can't click stuff underneath and then they also have some big advert advertising a scam website.
In this instance all you need to do is add "m." to the chaturbate url so the room will load in mobile, this will automatically disable any code and you can proceed with reporting
Edit
Although now I am trying with the m.chaturbate it isn't working, but it definitely did before because I had to do it to help some colombians who usually had 500+ in their room but due to this they had only 30 people.
Another method for if the "m.chaturbate" doesn't work, use your smart phone and it should automatically load on the mobile version.
