/48's handed out by ARIN are most likely in the PI range
that ARIN has deamed for PI use only. Networks are aware of
the PI block and have opened their filters to let /48 or
more specific through if and only if it comes from the
special IP block. That said...not everyone is letting more
specific than a /32 through no matter what IP block it comes
from.

More specific advertisements always stand a chance of being
blocked. I was
more interested in whether or not people know of places
where they are
actively being blocked and why.
That said- ARIN is handing out /48's- should we be blocking
validly
assigned networks?
