That's really a good point. Casinos having their account on this forum do earn some kind of respect from the community.
Most of the popular casinos have their accounts on this forum and I guess this adds an advantage the casino owners as well since they might get good traffic from bitcointalk users.
But there are also some casinos who do have an account on this forum yet are reluctant to stay active on the forum. This is what a huge turn off me.
Perhaps they have paid campaign managers to do the job, hence the "I'll just sit back and focus elsewhere" attitude.
Funnily they might spring up when it comes to promos.
