My gut reaction is that this highjacking was "opportunistic" and "state sponsored". The "actors" knew there wouldn't be any consequences.
It would be nice to "send a message" by banning an AS number. The hassles involved in revoking that ban and/or obtaining a new AS number would make it unlikely that such opportunistic bad behavior would recur very often.

It's simple! Just ban the number they've been assigned and that solves the problem once and for all!
...but what if they make a request under the guise of a different organization, to be assigned new numbe--
ONCE AND FOR ALL.
