ip hash commenters

I’ve added a little peice of code (from here) to my blog template to prevent “sockpuppets,” people using multiple comment aliases to pretend to be more than one person. (An innocent example). Basically before each comment you’ll see something like this:

The MsynZz is a “hash” of the commenter’s IP address. So if I posted another comment from that IP address, it would also say from MsnynZz — even if I used a different alias. The idea is that people’s privacy gets preserved, but it cuts down on the use of multiple handles, which Ifind deceptive.
