Aside from tormenting Maya (which I'd argue is a good thing) and her random beef with a CHICK MC that isn't on the M&J path she doesn't do much wrong. The prostitution ring is entirely voluntary (and we know Riona/Sarah/Mel enjoy it at least) and she doesn't randomly punch her housemates when things go bad.
Well, as voluntarily as it is, Quinn literally blackmailed Mona after she wanted to quit because she was afraid that she will reveal this, so she really want to keep all that a secret because it's still wrong no matter how voluntarily it is.
We still don't know the reasons of the girls who are a part of this ring, Riona looks like a drug addict so probably that's why she's doing that, don't know about Sarah or Mel so maybe they are the only ones who are doing it out of pleasure.
There's also Camila who makes it sounds like she doesn't have other choice and said she doesn't want to talk about it, so she knows it's wrong doing that.
The girls can be manipulated one way or another to be a part of this, we don't know entirely what's their motivation behind it yet.
Regardless, it's very wrong and i hope MC will put an end to it.
