The key to faucets is faucets that do their business "off-chain".  Using the internal services of different companies loses some positives with blockchain, but the savings far exceed the negative.

Just keep your balance building up on-site off-chain and then when it is worth something... move it on-chain to your wallet.

It took me years to figure this out, but alas...

I've paid some SERIOUS fees in batching TONS of little shits.  Also, your wallet will start to run like hammered hell with a ton of micro txids.  Trust me.  Not fun!
