Random.org does not use pure computer randomization functions:
RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive games and gambling sites, for scientific applications and for art and music.
I agree its random but people still have a hard time understanding and trusting it. I can't think of a single million dollar lottery that uses computers. Only balls. People can see it and everyone understands it. Does random.org allow for getting data at a very specific time. If not there is no way to verify what the person got is right or not.
The problem is that you have to trust random.org (or whatever else) and all the routers inbetween... (last time I checked, random.org didn't offer reliable https). More generally, the problem is that all source of true randomness are, by definition, not verifiable. That's why I proposed something that could be verifiable but extremely hard to willfully manipulate - both for those placing bets and for the lottery itself.
