Betnomi did some stupid things like selling user informations or giving it to other platforms. I don't think they had chance to come back after it was public that they sold the user informations or shared it with other platforms. Otherwise, they could have worked with the managers to solve the accusations.
Betnomi did worse shit than that which is why they don't deserve a second chance all things considered unlike BC.GAME who actually redeemed themselves after their debacle.
At this point, it would take a miracle for Betnomi to regain the trust of their customers in my opinion.
