Yep, There are only few old casino that survived promoting in this forum after a long time. I have saw so many casino that only stay in this casino for a while and disappear instantly, Maybe because they find no traction here? Gathering reputation and maintaining it is hard and this is why casino disappear overall because they failed to attract and get the trust of gamblers. Those casino who stood in this casino for so long are the one who got most of the trust of the members here.
This is normal, especially if all this time they have been promoting it on the forum and haven't gotten many new subscribers and there has been no significant development, so they will leave the forum by themselves.
It's not just the old casino in the new casino it's the same they create a JST thread then just give some response and after that walk away leaving feedback with no clear response.
Not a few ANN threads are displayed without representation and this is an error that must be fixed.
Actually there are many ways to gain reputation and trust from gamblers here, it's just that they don't want to try and try it, for some reason we don't know, but what is clear is that only a few casinos have been able.
