It's interesting that PSI routes it at all.  While IP ownership (note the
NON-PORTABLE below) and routing aren't necessarily interconnected, I
suggest contacting the block's owner and seeing if they know it's
alternately routed.  If they wish, they can request that PSI un-route this
block.  However, that would break whomever is using it.  The user should
re-number into PSI space, and this issue will go away.  If the user is
multi-homed, they should investigate the adivisibility of getting a CIDR
block which they can announce as an aggregate.
