We should ask their upstream provider why they are accepting this prefix!

Well, Korea National University have decided to announce 219.219.219.0/24 and inspite of me sending them e-mail, they still are. Ofcourse, I really don't understand why their upstream provider(s) is accepting this garbage from them.
A good motivation for such an action is the exchange of money.
These's policy, desired policy and commerce.
The most harmonious outcomes are when these things coincide.
What you are seeing in this case is either a misunderstanding, or a deliberate outcome of a commercial transaction. The former can be fixed by bring it to the attention of the parties involved. The latter has no such form of solution.
kind regards,
Geoff
