I laughed the hell out of my self when reading this post @OP and I'm so sorry I had to say that because with all due respect I really want to know how serious you were when you said you wish more success for the player and for yourself because no wan opens a business and wishes himself loss and it seems that's what you're doing ironically because from the tune in my head reading this post I could feel some tune of anger😁 just kidding.
I think there is nothing to laugh about on the post of @OP. This is a kind of marketing strategy of enticing readers to try their platform. Even other reputable casino do this kind of marketing scheme. They regularly announce players that just got a big win on their platform and it is also obvious that the casino is able to process this kind of winnings if it is trully won by a player since they publish it publicly.
I love the fact that you guys where bold and proud enough to share the winnings of a player which was against the house is something will have to encourage and I hope you pay more of this if there are more winners than expected.
congratulations to the winner and I hope the winner can also take some time to post on here to confirm this winning just as a user over here said earlier.
Good luck
But still I as one of the reply here, I hope the person who won the amount can confirm it and be able to withdraw the winnings. It will add more strength to the marketing act.
