An *AMAZING* number of routers will forward these things out into the Internet.

An even more amazing number of ISPs fail to do proper ingress routing to stop
borked packets from their customers entering into the Internet at large.

The fact that RFC1918 space (10.x.x.x, etc) isn't usable on the public
network (by definition) doesn't mean that you won't see inbound packets
with RFC1918 source addresses.
