Seems like they are trying to advertise using cheap / free ways and think that they will get gamblers and traffic to their site. I have seen multiple threads for 11Croco casino and they won't leave a good impression. Also, OP need to either buy a copper membership or hire someone who can design and post an ANN with graphics and stuff like that.
This is nonsense if they continue to open new threads, it will take them nowhere. I remember a while ago that I replied to a very nicely looking thread of the same casino with a copper membership profile. Two CMs here were among the first to reply to the thread to advise the OP to purchase the Copper Membership which he obliged. So why this again?
A goodly constructed ANN thread is a way to go here and they could look for a coordinated means of making users here campaigns for them. On another thought, maybe it is a conflict of interest where the persons involved are just trying to flood forums without knowing each other. This is possible when they have their targets as an employee or affiliates of the casino.
