Yes that might be the case, probably advertising their site here has a good result. Thats why despite of the negative feedbacks given to them, still, they decided to keep continuing their signature campaign, otherwise they already stop it because its a waste of money. Well, I hope gamblers are careful to only gamble in a trusted casino and not in casino that has bad reputation like this one.
They are working on the signature campaign for not getting any users from the forum. And I think their users are coming/increasing from out of the forum. It is because this forum is working to them as search engine optimization. And also for their negativity we are posting on their thread and we are mentioning about them. So it is also working as their marketing.
