A possible stick for ARIN could be that any AS that advertises space for B

Assuming the public even found out about the situation.

For ARIN to make good on this community goodwill, they'd have to

(1) publish the disrepute of the upstream who refuses to stop announcing the
downstream's prefixes.

Im not sure what step 2+ is going to be there, but I bet ARIN would become
unpopular with (1) above amongst its customers reselling bandwidth to other
IPv4 block users.

How many large carriers on this list would immediately halt announcing a
downstream-in-good-financial-standing's prefixes just because ARIN say's

I bet most wont even answer this question to the list here - most likely
have an official policy for this situation, and if they did, it's likely not
