Sticking up on their current manager would provably ruin everything they built so maybe better for them to find another good manager so that they can move on in this issue.
Since I guess the manager would struggle to retrieve back his reputation since looking at the reputations board he's really in bad position now and Betkin has been dragged on those troubles what their campaign manager is facing. They won't go anywhere if the person handle their campaign got a negative issue like this since people would provably avoid their casino and don't want to get involve with issues they are facing.
I saw the campaign and through your information, I read latest posts of manager and issues are like payment delay, and something happened with post counts, and request on post deletion. I did not look at it deeply but with quick glance, it does not look good at all.
That manager is an outsourced manager so Betkin can move on and hire a new signature campaign manager like Hhampuz, AB de Royse, icopress, Little Mouse and move on well. No issue from their side and their reputation won't be damaged by an outsourced campaign manager.
I don't know, payment sent with delay but perhaps there are other things.
The same campaign manager is alleged to control the official account of the casino in this forum, so practically he is the sole controller of all the information as regards this casino is at the mercy of the manager and they have to deal with whatever he comes up with, I think he sourced for this casino outside and then brought them to the forum.
This could be the end of Betkin here on bitcointalk since the officials haven't made any updates here in the ANN since this issue started some time ago.
