china pool had 100% donation for all
I've been there too, got payouts as well, but at a certain point things got bugged, like not showing the shares for a found block etc.
I did contact the owner and gave some tips what might be broken, but so far no e-mail respons.
A language barrier is sometimes hard to breach, let's hope he get's it figured out.
btw, at the moment that pool seems to be back up again and some ppl are mining, keep an eye on your wallets
