The issue isn't getting the AS blacklisted, the issue is getting people to
use the blacklist. Would you trust your router accepting entire ASNs to
someone else's list? Would your boss agree to allow others to shut down
access to a potentially major entity on the internet for something that
doesn't directly impact you?
I just don't see it ever happening, and anything short of that is no
deterrent for the above.
If you can't target the enablers with any kind of stick, then the only
other option is RPKI which prevents the actual hijack, but that has it's
own issues, due to the same benefits.
