Anyone notice strange announcements for 174.128.31.0/24

This was a test using unassigned IP block, unless I'm reading it wrong.  If a noc alerted on this it should have still be a low priority issue.  I don't see any issues with the way this was carried out at all.

But isn't this method kind of related to how an network from the
Mediterranean/Mid-east went about blocking what they felt was
undesirable/offensive content from entering their network?

i think herein lies the rub.  it is not prefix hijacking and in no way
should it appear that way to you.  i suggest tuning your detectors.  i
am told that path poisoning is used (futilely, we hope to show) in day
to day ops by folk to try to avert dos attacks.
