They need to, like it or not, unironically follow Hololive's method, even if the JP branches don't do it, Niji EN should.

Nazi tier management. I don't know how strict it is fully there, but it obviously isn't Vshojo-tier "freedom", so Niji is doing great on that front.

Choosing better people to hire. I don't watch everyone there but certain ones seem less retarded than others (Like Lazulight, Obsydia, and Doppio the only ones I watch). The ones who are stupid need to be dealt with in 3

The talents need to unironically moderate themselves, and not rely on management.
Hololive is lucky because it's been doing this since it was only JP. You'd see JP girls helping, "fixing", and correcting other JP girls (Senpais to the new generations).
This has been going on ever since and it's done with the Stars, IDs, and ENs.
And if I'm not mistaken we see it with kouhais "correcting" senpais more specifically, when Nene did her whole tracing shit, Iofi very much outspokenly talked about how she spoke with Nene in detail and basically bonked her worse than any manager could have
From the outside looking in, it seems like the Niji talents don't really correct each other when something is going wrong/they did something retarded, and either let management handle it or pretend nothing happened/is wrong (or they just blindly agree with them to not cause any "drama").
>tl;dr
If you ask me, the best way to stop a lot of the dramashit is that the EN senpais need to take charge and "correct" everyone else.
Then when everyone's corrected/nearly corrected, if another Zaion gets in, she/he will be corrected at the very start and the whole
>I can do what I want
attitude will die very very quickly.
And no, I'm not saying they should all be rosary clutching church moms, but going on stream saying
>Hey 4chan!
is terms for your management and all your senpai (Lazulight and Obsydia) to DM you and all collectively call you a fucking RETARDED NIGGER.
