Faucets have more or less been killed off since they essentially send what is called dust (very small bitcoin amounts measured in Satoshis). This clogs up the network so it is filtered out by most nodes. As it currently stands the amount paid by Bunny run would be less than the fee to send it (kind of like mailing somebody a 12 cent check with a 50 cents of postage).
More like "I'll mail you a free penny if you send me a self-address stamped envelope".
A faucet originally gave out free bitcoins for testing and introduction when Bitcoin was new, bitcoins had no established value and some were willing to share easily-mined coins to introduce new users.
Now the word has been stolen by scammers enticing people to look at ads and click on links, or even nonsense like "1 btc raffle faucet". When these guys do pay, they pay dust that is cheaper to discard than pay the additional fees to get it out of your wallet. There is no faucet, click "ignore".
If you want to test Bitcoin with free fake money, start it with the -testnet option, where there is still a faucet and the coins are useful because they are worthless.
