yeah, i also get the insufficient funds error - are you gonna refill, or are you done?
To be fair, the bitgolden and related faucets are empty for a day every now and then, but they do refill reliably.
So how about you? Maybe it's night at your place and you are asleep or something, so won't yell "scam" yet.
There should maybe be a fallback plan though - or at least a message addressing that.
Could you make a statement concerning that?
