Let's be honest, this is a niche forum, there are very few children on this website, and certainly even fewer are unaware of the risks of gambling. Yes, these people have a chance to lose a lot of money, but that's their choice. They also stand a chance at winning a significant amount of money if they gamble carefully at the most opportune moment.
Judging by the post quality recently I think the age demographic has significantly decreased. I'm not necessarily saying this is a bad thing, although certain users aren't exactly showing they are mature, and experienced.
