Why not use someone else’s IPv4 addresses?  Really.  What is wrong with using
someone else’s IPv4 addresses if it achieves the need?  As far as I can tell
nothing.

Other than the fact that a /24 is being advertised out of one AS and it's part of
some other AS's /14 and looks suspiciously like a hijack?  And we currently don't
deal well with identifying and preventing true hijacks and mess up false positives
a lot of the time?

I’m curious if you actually read the example of use of another’s IPv4 address before
starting talking about hijacking addresses?
