The misuse of AS numbers was not seen (maybe until now...) as a frequent event (and thus a priority),
Then you have not been looking at various announcements of Chinese address space and asking yourself whether or not you think that it is plausible or not that a large Chinese ISP would be buying transit for a small subset of their space from this small out-of-region hosting company :-(
but if someone is (mis)using an AS number that belongs to a third party, then it should also be stated in writing that this practice is a violation of RIPE policy -- and of course, allow a path for the affected party to issue a report about that.
AIUI the current discussion is intended to allow the proposer to refine what they are proposing... ... in a world where RPKI is gaining some traction, the misuse of AS numbers (to tag onto hijacked prefixes) is going to become more common. I can see no reason to separate out this wickedness. -- richard Richard Clayton Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
