Nobody has abandoned this thread.
But it really looks like you have abandoned this thread as the way you are bumping this now. Your posting quality and replies were better in the past. You are bumping this thread without any valuable content now. Post some big wins screenshot and make promotional announcements occasionally to make the thread alive. BTW, there is no promotion at Punt.com. When the 'challenges' will be available?
If gamblers do not ask anything here or they have nothing to discuss about this casino, then the OP have no option but to bump the thread. However, he should think about why other gambling ANN threads are always active and there is no activity on this thread.
One reason which comes to my mind is that fewer people are playing on this platform and hence they do not discuss anything here. Also, Punt needs to have some sort of marketing campaign / Signature campaign in order to attract the gamblers. The competition between the gambling sites is quite high and hence they need to have some budget for marketing purposes.
I think it's nothing illegal to bump your own thread by current updates and promotion of your own casino. One thing I can see why other gambling ANN threads is way active than other ANN threads is because people have something interesting to talk about like new updates in the casino. If gamblers knows that there's a new update it basically means that they are active in playing in the casino and want to know the experience of other gamblers. Even if there's an active updates posted by the casino representative here, if no one is interested in it, obviously no one will talk about it or have sentiments with it.
