For people that don't know. The router will try to get the most specific
prefix. This is by design, not by accident.

You are making the assumption of malice when the more likely cause is one of accident on the part of probably stressed NOC staff at 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 /24 route is leaking outside of their AS via PCCW due to dodgy filters/communities.
