Why would he ? Signature campaign manager is responsible for the campaign and payments to those who participate in the campaign. If any issue in payment of campaign, only then you can held the campaign manager responsible.
Becoming a campaign manager, does not mean that he has become the owner of the business. He is only doing a Job.
Right on point! As far as I remember, this will be the second time that roobet is running their sig campaign. Though the first one is short lived but it means they are pretty serious in doing business as they are now holding their second round of campaign. Campaign manager has no responsibility regarding payments within their casino but if for example, roobet will screw its customers, then the campaign manager has the prerogative to stop the promotion and clear things out. If he will continue to do the campaign even if he found out some wrongdoings, then it is the manager's reputation at stake also. However, knowing Hhampuz, he will do the right thing.
