Allowing ASN to blackhole a prefix based on AS sets is dangerous from my point
of view. In the RIPE database you can add any AS to your AS set without
verification. Ok, it doesn't make much difference because most IP transit
providers also filter on the AS set, but a worldwide announced /24 prefix is
much more visible than a /32 blackhole route that is only announced to the
participants.
