Yes, and she has to know well the difference : ). A friend model had many warnings from CB after working with a studio last month, she just didn't ask to the studio how they made traffic.
Another one uses an affiliate who certainly advertise here and there and RT her on twitter (smt like elitegirls.live or one of this sites who encapsulate CB)
I rad also this chaturbate100 page (during this thread about the way to count tk) and they displayed a weird warning if I remember well. But now I can't find it anymore as said MousyLion.
