Remember gambler-protect or whatever his name was? Dude was around the gambler world all the time trying to sabotage or blackmail his way to wealth and bothered casinos as a living, that was literally his way of making money, dude is banned and gone and nobody even remembers him that much, over time nobody will remember him. So, just ignore them and they will be gone out of your lives eventually.

In the topic next door, there was a discussion about why some casinos do not want to open topics with announcements on our forum. Perhaps the presence of trolls is the reason for this.
