I can suppose that they are busy and don't have enough employees to handle media. Their bounty campaign has ended and according to telegram channel they have lots of DM and issues with stakes and distribution. I can suppose that there are 1-2 persons responsible for social media, forums and bounty, and they don't have time to read last pages of this topic or know about topic existence in scam accusation section. Right now they are looking for more people to manage different language telegram channels. They are just busy and once sort that little issues there, will get back here. Just my two cents.
If they opened their announcement thread here they should have people who are in charge to check this thread regularly. They can not open it and abandon it for community. It is harmful for their casino.
I suggest to try to contact their admin in telegram, they are quite active there.
It's can be a start to get contact point and inform them about what's going on in this thread, on this forum. They should check all things here and resolve such accusations against them.
If you check post history of a guy who is saying that Bitgame is scam, you would find that he has some issues with gambling casinos all the time. Looks like every gambling site cancels or freezes his withdrawal, cancel bets, steal funds.
It is a good point because a bad history can show that one person is unreliable. And if history is full of inaccurate accusation, it can mean something. However, the team must check and resolve it all here to clear accusation.
