Oh wow. I've never heard of Tango. That sounds insane to me.
I have no clue what tango is.
I split cam, and once in a while I forget to turn off to another site. It sucks. When I see I've done that, I block every single guy that stayed and watched, without alerting me, because it was not something he paid for, or had permission to be a part of. The few times that have happened, my room numbers have stayed normal for the time of day, so thinking they tripled because you were possibly there, sounds very unlikely to me. I've been doing this 12 years now. If her placement bumped up, or it hit a certain time of day where everyone jumps online at once, that is more likely the reason for more viewers relatively suddenly. Or she took of an item of cl.othing that was on before

Yeah as soon as models take their panties off, the room count triples, quadruples, whatever. Everyone wants to see some pussy for free.
That is just some extra information about spilt camming, in general. Different sites have their own specific rules. I don't patronize or work for sites that try to come down on models for very benign and understandable stuff, or demand exclusivity in any way. Because that can severely impact a models average hourly earnings, and make the site not a viable option for her any longer.
I think you seem like you may be reading a bit much into it.
It doesn't seem worth all this thought, time and effort to me.
