Guys: I realised that the offending overlay banners use absolute positioning.
That means that depending on your screen resolution it will show up at different locations.
I have a laptop and for me the buttons appear right on top of the standard SIGN UP. Chaturbate Support might see the buttons in the middle of the screen if they have a bigger screen and therefore not take action after you report what you (rightly) believe to be an offending banner.
