Why do you care? Are they forcing you to wager your money? Did they put a gun on your head? No. Whoever is falling for that scam and wagers more that he could afford to lose deserves to lose that money.
People will try anything, no matter how ridiculous it may seem. There are always a few people who fall for these scams.
In the end, the only way to truly prevent these from happening is not by censoring, because in the end this is a democratic, open world but by raising awareness so that people can educate themselves, even if they're new comers or simply want to get involved etc
So, as long as nobody is forcing anyone it is a free, open and democratic choice that each of us has. We each can decide to either support this or not...
