They hace stopped promoting here as they have a lot of scam accusations and their announcement thread is full of complaint. As a rrsult they are not getting enough return comparing to the investment to the part8cipants. I think mainly for that reason they have stopped promoting their gambling site on this forum.
Let me say that to a great extent, you are right, but I also think it will be more accurate to state the fact as it is, and that fact is that, 1xbit have stopped promotion, not only on this forum, but also in every other platforms where personally used to see their ads before. So, let's say in general terms that the complaints didn't only make them loss traffic on this forum alone, but they also lost traffic in every place they were advertising on.
I say this because, if they were affected only on this forum alone, they would have stopped advertising here alone, but keep their ads in other places where they were still generating traffic from.
