Isn't there anything the mods can do to stop it?
Well, there are too many sites and topics to be stopped, just look at the Investors-Based Games thread, 99% of them are scam. We should learn to recognize for ourselves what is most likely to be scam instead, especially more and more 'scamsites' are on the rise now.
For the case of faucets, I would rather use those that payout instantly to micropayment platforms like FaucetHub, just stay away if you are not sure it is paying, especially if they have those high payout threshold.
