There is nothing wrong with prepaying and it is a serious error to suggest that. There is only bad business practices. Prepaying includes a calculation on both sides that there is a possibility that either side will act dishonorably; or die; or deliver poor performance; or deliver out of the box better performance than anyone would have guessed; etc. These things are part of the calculation in making the deal (unless you are a horrid business person and don’t think any of this is possible).
People can get screwed by post-paying, or pre-paying, or even pay as you go. Non-news flash here: unscrupulous people can figure out a way to be unscrupulous regardless of the payment scenario.
Allegedly bad affiliates should be pointed out with the same criteria that allegedly bad casinos are. But there is a problem here. Posts similar to the first one here could be used as a means of extortion in a business negotiation between parties, particularly if the paper trail is not as clear as it may be here. I would hope people in the future would either name names, or not. These general posts of major problems help no one. Even if it pressures one party to behave in the specific situation, it does nothing to help others in the future avoid the same problem.

Mildly off-topic, I’m not understanding how a manager can be personally owed $4000 by an affiliate. Wouldn’t this be a debt owed the casino group?
