Real Madrid doesn't work that way, it's only certain season ticket holders, the ones who can take decissions, the club is ran in the old way. And votes are casted with papers and raised hands.
What's the scandal? Calderon the chairman managed to enter in the clubs meeting people without right to vote. Lots of them, and their function, besides voting yes to the numbers Calderon gave, was to insult anyone that was against the chairman.
MARCA has unveiled everything

At first, Calderon said he hadn't anything to do with those people, but MARCA yesterday showed how everyone of them were closely related to him, or his son, even showing pics of them together

So Calderon has been caught. In fact, he was caught a long time ago, but in this country, until Marca decides to remove someone, nothing happens.
Here, a youtube video. Even if you don't understand SPanish, you can hear the insults. The people whistling and insulting are the people put by Calderon to try to silence the opposing voices.

I hope you understand the explanation

P.S. For instance you can see an old guy that breaks his paper and goes, saying
"I've come to make a criticism, not to be called son of a bitch while you allow that". and he leaves, while being insulted by Calderon's muppets.
That's what happened with anyone saying anything against Calderon
