Great answer.  Thanks.

Committing to pursuing a policy of weaponizing BGP would have triggered a
serious "terms of service" violations that would have effectively ended
your business swiftly and permanently.

Tip to the RIR policy folks, you may want to make this point very crisp. A
BGP ASN is the fundamental accountability control in a inter-domain
routing. Organizations with repeated offensense need to have their ASN
revoked, and further there should be controls in places so bad actors
cannot acquire "burner" ASNs.
