Its not just bitcoinwisdom not picking them up, they also aren't on bitcoinity any longer. Thinking the biggest volume was happening at OKcoin anyway.
Has Okcoin added fees to all trades in their exchange yet? Maybe the reason theyre still there is because it was only Huobi that added fees and has stopped all the fake trades. If Okcoin gets rid of all the fake trades maybe their volume would be so much lower. I suspect that BTCC really has the highest volume in China.
I think the traders all over like OKcoin more vs BTCC, maybe BTCC has more actual volume coming from inside china. Either way its pretty close if you check bitcoinity.
