Can a bettor reject being unveiled to the public?
As far as I know, if you win large amounts of gambling, it should be published, because it involves paying out large amounts, different from winning small amounts, the reason is because the casino is responsible for the money that is spent and that enters the casino every day.
For some gambling industries, to spend large amounts of money, the parties responsible for the casino and finances must know, because some gambling casinos work with partners or investors who invest, The money spent must be published in the media and this will show the public that their casino is honest and responsible for big wins for its users.
Casinos have a nominal amount of money that must be paid out in small amounts per day, so it doesn't have to be published, but unlike users who win large amounts, like it or not, publication is required.
Yeah, it must be publicized but it's also at the discretion of the winner if he wants his face hidden. I have seen this before where the winner was awarded in a stage but when it was put in the news the face of the winner is blurred and I think that's okay for security.
There must be a choice for the winner to have that kind of privacy especially if he thinks that many people will take advantage of him or he will be in danger when they knew it was him/her.
With that, the media must comply or else it will be their business who can be sued if they will leak out the face of the winner and jeopardize his life.
Most of the national lotto winners that I've seen have blurred faces while some do come out after a year or two telling their story in public and there's even a series about lotto winners here in our country and the story behind it being televised weekly. I guess they do that after they secure all the money that they won especially their will in case something bad happens.
