Ah, I just heard this one. I don't follow such betting signal groups but the cheater mode with such affiliates sounds new to me. Is it possible that some players really believe in signing up for an account and depositing their money to a site they just found out about? It is possible that fraudsters provide several accurate bets so that they are more confident in following them. and when given a referral to play on a new site they will follow it happily. Their target is clearly novice gamblers.
This provides an advantage for fraudsters with affiliates and it could also potentially be that the gambling sites they promote are also fraudsters and clearly this will be detrimental to players.
