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.
Its not easy for BC.GAME to regain their reputation since they face a lot of criticism before but they manage to satisfy people on performance also other things that needed to do. That's why right now we can see them running successfully or shall we say get back to normal form. What betnomi did is a huge mistake that's why same for people who doubt about their current reputation I also don't believe that they can regain back the trust of people since there case is severe which a lot of people here cannot take to handle. Selling the costumer information is risky for the part of those people since they might experience an exploit or receive a lot of unwanted offers that can potentially compromised them.
