I have questioned faucetbox on their thread and they replied today. Not sure if true or not, but you guys can judge
Seen this?
Mysterious
Have you been ddosing microwallet? Your site is cool and innovative, but you should play by the rules and not resort to ddos
What can I say... We didn't ddos anyone. I believe that our service is better than Microwallet. Lots of people were already tired with them, Microwallet future were uncertain in past few months, so I really don't have to do anything to Microwallet to compete with them. I'm just giving what I think is a good service

BTW long-standing DDoS attacks aren't that cheap, I don't believe it's worthy to DDoS anyone in faucet business. And as far as I know, if a site is DDoSed, most of the time it would be totally unreachable. And Microwallet is reachable, they just don't payout too often, so I doubt that there was any DDoS at all.
