If the Chinese wish to completely refute their involvement at Government level perhaps they could use their "Great Wall" to filter out this traffic.
It would appear to be good at stopping users inside China from accessing "un-patriotic" content from elsewhere, so let them show willing here and stop criminal activity from coming out.
Until then all Asian (& Eastern European) access to my sites is banned >/dev/null and beyond!
Would be 2c worth but the GBP ain't so good after the budget!!!
