Providers trying to "steer" traffic through their peers, upstreams, or
exchange points is nothing new.  However, this caught my attention.  If
Sprint isn't pre-pending its routes with Sprint's ASN, who is?  It is
generally considered ill-mannered to use someone else's ASN without their
permission.  Traditionally, pre-pending is done with the pre-pender's own
ASN.

If nothing else, to help track down the party when evil things happen.
