Would there be a high chance of match fixing due to no crowd? Just a thought.
Match fixing chances does get increased or decreased due to crowd. Even if people do not watch the match live in person, but they can watch it live on TV or later recordings on you tube, so there is not much difference.
Anything if this sort of things happens in any sport let it be will get reported irrespective of the crowd presence or not. Nowadays we have camera and will be telecasted on various platforms so anyone will get caught of wrongdoing if so tried to do it. And not many would like to take that risk and spoil their reputation for the rest of their life.
