Seems to me like that's asking for trouble, offering gambling services with Paypal withdrawal.
It looks like no inputs.io deposits made overnight got through to Just-Dice. I processed them all manually this morning, and added an exception to the CloudFlare DDoS protection to allow inputs.io through unchallenged.
I've been unable to test it since doing that, since inputs.io seems down at the moment. Probably they're being DDoSed too.
As for being "MIA", I sleep sometimes. And to be honest watching the site get abused so thoroughly is more than a little upsetting.
Just tested, they're working. I'll add that to the API documentation.
