This is pretty standard behavior, really.  I haven't seen any real
problems because of it, but I can imagine it being an issue.  It is
easily solved by blacklisting, however.

All the hits on that page are for dccproc.  Are there others that are
that broken?  I don't see any bug reports from you about it, or actually
any bug reports about this issue.  Can you report it if it's a problem?

The first hit gives you explicit instructions on how to do it.

It is getting more and more common, and most of the world doesn't live
in an ipv4 saturated country like those in Anglo North America and Europe.

Not particularly, unless you actually have an addressable machine.  And
if you have given a machine a public IP address, surely you've thought
about this and taken security precautions?
