and again I point to the above rules. What your network can't handle
'scanning wise' is completely different from what the network I work on
can handle.

If your network is being jeopardized by some level of scanning they fix
that, but that is a local decision. Blindly stating "large isps filter
port X" is just disingenuous, there are certainly cases as exceptions,
most of which end with the ISP in question saying: "Wow that was a lot
more painful than we thought originally:("
