I don't think much can be figured from this. When I first started maybe 5 years ago, credit cards were used and they figured probably one had to be 18 to have a credit card. Next came PayPal an Neteller--so if the funds were released back that way, one was of age. So Basically, I don't think they asked. They have a disclaimer about the age on most websites-(I think). Not one time did ANY book ever ask me for a faxed ID and/or Utility to process my payout. But that may be the wave of the future as I notice that Bet PanAm says they MAY require it. So I decided they were ano go.
