Corruption is a kind of a hard control mechanism of subordinate people as at any moment an unfit person who has stopped following unspoken instructions can be sentenced to several years in prison and in some countries more severe punishments can be imposed. That is why corruption exists in all countries and absolutely in all spheres of our life. It is just that some countries are more thorough in hiding corruption cases.
We are talking about corruption in sports, and normally our understanding is that what is happening is "sports fixing", some people may not be too concern about it, but for gamblers or sports bettors, this is a big thing as they can use this as their basis on making a decision, and I believe that some sports bettors believe that no sports are clean or safe from sports fixing.
I understand this better than you think) Corruption in sports is not much different from any other. If a sports team, coach or boxer agreed to a fake match for the sake of money, then after that he can be managed as he will do anything not to spoil his reputation. If an athlete is caught in this vicious circle, it is not easy to leave him, because he becomes a puppet. Corruption in sports is punished no less severely than in any other sphere.
