The newest one is, they will ask us to join a certain sports gambling site under their affiliate then he/she will provide us with daily or weekly "fixed match"
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.
Anyone who follows these signal groups to get predictions for fixed matches is doing that at his own risk. A gambling site that gives bets for fixed matches cannot be trusted because they got the bets illegally. Anybody who can access or offer such fraudulent services can easily scam his clients. The victims are not just new gamblers but many old-time gamers fall victim because of greed and in some cases, they give accurate predictions. But it is better to do your work yourself and place your bet than depending on signal groups.
