But till now I have not gotten the understanding that how those leagues can be manipulated and if such thing happened, there will be a serious sanctions for the people that did it so I believe everyone in the league must maintain. But how can a player sell match? Because as for me those match can't be manipulated. Is it that after selling, they will perform below standard? Sorry for asking all these because really I don't really getting the logic here.
From my understanding, small leagues can be manipulated and that's why casino avoid leagues that are not recognized but it doesn't mean that big leagues can be free from manipulation too, it's just that such big leagues can't be manipulated easily. There are eyes on players when they make mistakes that looks intentional and once they see that you have done something that warrant investigation, the player suspected will be investigated.
I don't think a season that is plays for 6 months will go one day in all of the 38 weeks without any form of manipulation. If the player doesn't do it directly, they might do it for somebody that is not close to them. After all, it's not like all the players have the same capability to play in every competition, there are teams that doesn't reach the top of the league neither the bottom, if a player from any of those teams get a yellow card, nobody will suspect the player.
