Well, the intention *is* that "if the IXP supports black-holing, please do".
In implementations like DECIX', the neighbouring IXP participant does not
have to do anything in particular, except "accept the prefix with the
black-hole nexthop".
Maybe more along the lines of
This well-known advisory transitive BGP
community, namely BLACKHOLE, allows an origin AS to specify that a
neighboring IP network or IXP that has appropriate mechanisms in place
is requested to blackhole a specific IP prefix.
