I partially agree that models should police the chat in their own room. If it's a small room with not a lot of users, that should be easy. However, I have seen popular models with chat moving like crazy with tips and messages and not to mention spams from grey accounts. if the model has to focus on reading every single message and filter what is underage and what not, it seems distracting and people can lose interest quickly. Also, there are models who masturbate with their eyes closed for like a min or two and the chat probably moves 1-2 pages already. Should she go back and read every single one and report underage comment? Probably not so practical.
I think CB should have some app/tech to detect inappropriate stuff to help broadcasters as well. I also think CB should not let users create accounts so easily because i have seen some models banned an user for saying shit then having the same user come back in less than 1 min with a different account. Imagine you have to constantly deal with this in your room, how are you going to focus on your work and satisfy other users then?
(I'm not a broadcaster btw).
