If the story is actually true, then that's a fantastic result for the player. Still, I think this is purely about advertising he wants to make for the sportsbet site.
Why would someone post how much money they won on a gambling site? If I had won that much, I would prefer to keep it to myself. I certainly wouldn't want other people to find out that I would have won that much money. You can only risk it that way. Well, maybe people think differently. 1.4 million is a lot of money, by the way. Will gambling sites actually pay that to players?
I think this is all about advertising the sportbet because I don't see any need why someone will post the amount of their winning online, any way he may not be at risk posting in this forum since no one knows each other personal identity.
But then this is a good win for the ops after a ling time of gambling without winning such an amount.
