Even without reading the faq I think everyone's already aware that nutaku is shady, so this kind of shit shouldn't surprise anyone. 1 year is a long time to leave an account inactive, but why is that they didn't just close it and delete it entirely instead of just wiping the balance? Because they're so thoughtful they wanted to leave you something in case you decided to come back and spend more?

Your nutaku account is forever, but your money isn't; they'll always want more of it.
