Hhampuz is the campaign manager, and his feedback is related to his position and current relationship with the service provider. I do not see his action as a vindicating scam. Moreover, if I'm not mistaken, Hhampuz has, on more than one occasion, refused to cooperate with services that looked suspicious or had negative sentiment from a number of prominent members or the wider forum community. He even went as far as repeatedly paying campaign participants out of his own pocket when the project owners turned to the dark side.
Hence, accusing him of siding with scams is completely unfounded, as he has demonstrated time and again that he values his reputation above the money he earns from campaigning on a weekly basis.
As for this particular case and the accusation that Stakemeharder made against Rollbit casino, I really can't pass my judgment because, as LoyceV noted, the whole case is kind of messy, and we have bits and pieces of information shared across multiple posts, so it's challenging to form a conclusive opinion. Based on the few screenshots I've seen, there does appear to be some unusual betting activity, as risking thousands of dollars at 1.003 or 1.008 odds doesn't seem to make much sense unless it's a way to take advantage of rakeback. Now, whether this alone justifies banning a user and confiscating their balance, I cannot say, and there might be additional reasons that the casino is not disclosing.
My only suggestion is that Stakemeharder should try to present the case as clearly and transparently as possible, and also seek stronger community support or the opinion of a third-party mediator.
