Agree, it's hard to convict these people as they will surely not gonna admit they are trying to rig the game. Though it's obvious, they will only be accused of a crime if there's enough evidence, now the question is, what evidence will they use against these players to prove they are rigging the game?
Taking into account that we live in the digital age and that most people do not take their security seriously there could be a lot of evidence that could suggest that whoever is suspected of rigging the game, whether the players, coaches or referees were guilty of it, we will have a lot of evidence to prove it, it is similar to what couples go through it now, finding that your partner was cheating was harder in the past as you needed eyewitnesses, but now the only thing people need to do is to grab their smartphone and take a look at their messages and they can quickly find out if their partner is cheating or not.
It is fortunate that the development of technology has developed rapidly, so it is easier to find evidence of people involved in rigging the game.
There are many ways that can be used to get evidence, usually tapping a smartphone is the most effective way to get evidence. Because usually
there will be conversations about rigging the game. Can also check a suspect person's bank account, if there is a suspicious flow of funds it can
be investigated further. So I believe everyone involved in rigging the game should be caught and given the appropriate punishment.
