yes and those same gambling sites that adverstise on the gambling section on this forums are the same ones that have so much threads that prove them to be scams.
for example 10 seconds searching and i already find this:
https://bitcointalk.org/index.php?topic=5262142.0again 100times i ask u for good sites and u cant proved me lol because they do not exist!
Even if we disregard the fact that the thread you linked actually has nothing in it (details, evidence, story of any kind), it's not terribly difficult to find any "<x> site is a scam" thread since you'll get those complaints - similarly to yours - when it's not necessarily equivalent to an outright scam but rather when it's an issue on the player's end.
