This is by design, not by accident.You are making the assumption of malice when the morelikely cause isone of accident on the part of probably stressed NOC staffat 17557.They probably have that /24 going to a gateway walled garden box which replies with a site saying 'we have banned this',and that /24route is leaking outside of their AS via PCCW due to dodgy filters/communities.
