According to what I have read so far it seems like users are not happy because of two reasons:

• The possiblity of newbies getting scared to even try out gambling or stop gambling totally because of what they read here in the forum
• Spamming

The two reasons above are reasonable if you ask me, but first we must understand that anyone that was able to find their way to bitcointalk can also reach other plat and I'm sure that there are other platform that still talks about the effects of gambling addictions, it's not a secret that should be kept hidden and it's best that we educate newbies so that they can learn how to control themselves. and like the popular quote says "A stitch in time saves nine".

As for the spamming; if a new thread that is already in existence and still active is created then the best solution would be to simply report it to mod for the thread to be locked or deleted and the Op of that thread should be directed to the already existing thread. But the issue we are going to experience is that many users would be hesistant to report the thread as they could easily use it to complete their signature weekly quota, and that's why you still see some thread that should have been reported for it to be deleted is still active.

TL;DR if an already existing topic is created click "report to moderators" and report it, as simple as that.
