Which almost no one would ever see.  If they were really worried
about this ISP's would have raised enough noise to prevent registries
accepting microsoft.com.sucks.example.net.

If they do get you.suck.isp.com then the ISP really should be
thinking about why one of their customers thinks they suck so badly
that they are willing to name their machines with you.suck.isp.com.

Additionally you.suck.isp.com is unlikely to make it into logs as
most logging software actually does a forward checks which would
fail leaving just the raw IP address to be logged.  Additionally
it would also tend to restrict access to sites which care about PTR
records existing as they do check the forward name to see a address
matches with the PTR record.

In reality this is just a lame excuse to not do the right thing
which doesn't stand up to scruntiny.
