Eh mostly the ones without cause were people that tried to push too hard. I know of like 3 mods who quit, 2 who were banned, like 7-8 VIPs who left for various reasons (her attitude was changing, stopped playing with viewers, didnt hold her word, etc), Dank who she use to duo with stopped cause she never raided him or helped him in anyway while he always supported her stream, talked to some of the money guys who left cause of their interactions with her. Sadly, I was one of the money simps at the beginning but nipped that.
There are some theories on Bearman. I know they have met up, don't know what happened beyond that, I do know people that were previously in her inner circle said she was leading him on for the money most of the time. Dude is married with kids. It's no bueno.
And shit I can't find the reply now. I should stay off twitter, it's never when I am like "let's post something nice!"
