Something like this is probably not very widespread (has anyone seen it
in practice?), but I still think that for tracking purposes, ptr records
are useless. IMHO.
You are right, people can change it to be whatever they like, potentially.

What if they wanted to change the IP?

Think about what you said, and you will see why you are wrong.
