Just tried the 3 mentioned faucets and I were able to have the reward in my account on these two with no problem:
However on makefreebitco.in , there was a different error, I didn't get "invalid address" either but after hitting get reward the page only reloads and if i'm not wrong the faucet is not using the faucetboxs faucet scrypt and in appears to be something else even though they pay using faucetbox
