I just registered to add my 2 cents.
I happen to know them. Pretty well.
E-a is I-b's sister, they have different fathers though. The woman usually standing in the doorway of I-b is their mom. E-a coached her younger sister about the "business model" that she has invented. Obviously it worked amazingly well, as both sisters are now in top 5 highest earning (human) models of CB. (The #1 is, as we all know, our favourite hentai girl Melody, but she had herself removed from the CB100 list.)
The tipper named t.... in I-b's room is also a relative, pretending to be a random tipper from Germany and doing all the pep-talk for other guys to tip. They rotate tokens between each other (the tipper and the model).
As far as I know, on the other hand, E-a does not rotate tokens and does not have any friends/relatives doing any pep-talk.
In Russia, news travels fast though, especially news about people getting rich. Gossip spreads like wildfire, so now there are conflicts boiling, as there is another russian girl copying I-b's room. The copycat's name is whats_her_name (no advertising intended). Because of this, I-b now created a new account under a different name and had her previous account's followers etc transferred. But there are numerous others who are following E-a's business model now, or at least trying to.
E-a is not wearing a toy and she has been saying it herself to people who know her. But I guess it's not really hard to detect anyway - notice, how she starts her over-the-top reaction as soon as she hears the distinct sound of 500 or 1000 - even though theoretically she must still have her "toy" reacting to a long line of smaller tips. There may be a dozen of 100's in a row but as soon as the Yee-haw hits, she goes Full Steam Ahead as if the vibes levelled up immediately. But it's her business model and it's not really against the ToS in any way, shape or form. It's a show and she is getting tipped for exactly that. Maybe shady, maybe questionable, but... business is business and she is NOT breaking any CB rules.
However, she does get a lot of hate. Maybe more than any other model. She even has a FB hate group with her username... lol
She is tiny and looks childlike in real life, as if the time stopped with her, but her character has changed a lot within the past few years. She used to be smiling and outgoing, perhaps a bit submissive and trying hard to be likable. Now she is quiet, won't really socialize much any more and seems pretty bitter when she does go out.
She has Russia blocked and she often goes through her viewer list when she has nothing better to do and kicks everyone whose profiles say they're from Russia. Someone mentioned her being absent and changing, the time she took a bit of a break was the time when her family found out about her camming and again - the news spread like a wildfire. It was frowned upon for a long time but now, she obviously laughs all the way to the bank and has moved on from being mocked to being envied and looked up to.
As you see, even her mom is stepping in and performs for the camera when her younger sister is taking a snack break or just a rest. I don't have any info whether the younger sister and mother are wearing toys or not, yet I believe the sister does but mom does not.
It truly is a genius business model, hands down. This young woman has brains of Einstein.
PS E-a doesn't use a mod, there is no "boyfriend in the other room". She controls it all singlehandedly. Literally. As you can see, her one hand is always out of the video frame. There's a mouse pad under that hand and she works really quick copy-pasting the phrases she doesn't fully understand into a translator. However, her English is pretty decent anyway, so she doesn't need to translate much to be able to determine who to silence and who to kick. When she goes to kitchen to get something to eat, she logs in to her account from another device and this way keeps an eye on chat and kicks the misfits.
All in all, she is phenomenal, imho, and in many other people's opinions who know her. People look up to her now.
If you have any questions, I can try to give my answers, however, I won't reveal any names nor locations.
