[members-discuss] Our AS is in a macro that we don't authorize.

To the best of my knowledge, there exists no mechanism in the database
that lets ASN holders to authorise or deny the inclusion of their ASN
in someone else's AS-set.

For example, nobody can stop me from creating AS-set «AS-ALL-ODD-ASNS»
containing AS1,AS3,AS5, et cetera. And nobody can stop me from
instructing my peers and upstreams to use that AS-set to build their
route filters facing my AS.

This facilitates hijacks by malicious actors, of course. RPKI won't
help as the origin AS is easily spoofed.

You are of course free to attempt to chase down the maintainers of the
offending AS-sets and convince them to remove your ASN, but over time
it likely becomes an exercise in futility. C'est la vie...
