oh boy. What if I had 0.1BTC in each of those accounts, but they were all accumulated through hundreds of transactions? What's the point of BTC faucets if you can't do anything with the tiny amount they give you? If it can never move out of an account, it's just a waste of satoshi, right? I would have thought it would make more sense to impose a fee on large transfers rather than the small ones (tax the rich, not the poor, etc).
The point of faucets is to lure unsuspecting unknowledgeable people with useless payouts so they can sell add space to advertisers and rake in large profits for themselves. The operators of the faucets know that the amounts they are paying out will cause problems for the recipients, but they don't care. By the time the recipient realizes the problem, they will have already spread the popularity of the faucet through word-of-mouth, and will have already earned a significant income for the faucet operator. The frustrated user has very little recourse and moves on a bit wiser for the trouble.
