Seems silly to give us a hash but not the actual IP address.

Privacy? Staff can still expose people's alts provided they're using the same IP address, don't even need a scripted tool either since a lot of staff can figure it out with view attributes.

Malicious scripters using your IP? There's at least two ways it can be retrieved via script still.

IP Addresses are much easier to compare and look better in logs as well. It would also allow us to create tools that let us search whole subnets.
