This is absolutely an issue with Xbox Live/Sony PSN or RBLs used by mail servers for reputation purposes. For better

Talk to someone who has been sued for downloading or sharing movies.  They'll swear on their own grave that one IP 
can never equal one user. ;)

I’ll swear it’s a horrible assumption.

Personally, I use many IP addresses each day.
Some of them are also used by others.
Some of them are not.

Equating IP Address <-> Person relationships as being anything remotely resembling 1:1 is beyond absurd. To do so with 
an IPv6 /64 is even more so.

Considering it to be reasonable or “good enough” is so far from valid I don’t even know where to begin.
