Performing such function based on IP would make no sense. Frontier, Time Warner often change IP addresses based on lease time, outages, then there are places that proxy for a more anonymous web surfing experience of privacy for surfers.

There are a variety of ways to overcome such matters. One that pops to mind would be browser extensions using key/value pair hash which would be pretty easy to code up.

In as far as commenters go, I am often simply amazed how many webmasters love the freedom the web provides them yet are clearly not in favor of freedom of speech in their blog/interactive venues. They are against government/legislative boundaries yet choose to enforce boundaries.

Slammin' people with email saying their post is approved is a sure way for them to find other places to communicate. Automation of "intelligent" comment passage really isnt very sophisticated algorithmically but in order to implement it properly would be a core type function as there are several core areas of data that need be addressed in making the code substantive enough to be difficult to defeat since the source is open and available.
