I have to agree because even if you manage to remove IP Tracking from the software, your webhost logs everything committed to your site. But, there's no way to remove it because the ACP records everything ... in order to remove all IP Tracking, that's going to involve someone creating a "Full Mod" for that and I doubt anyone would create one because most would have no reason to use that feature.
I would say that if you're concerned about that, then you need to find a forum software other than IPB.
It just sounds like someone is asking for this in advance because they think someone is gonna request logs of these users. They might want to think about hosting their website outside the country they're worried about.
BE WARNED: If you remove IP Tracking from every aspect of your forum software and you are in a country or nation that requests information about this member or that member, as it pertains to their IP Address and you don't have IP Tracking, the owner of that website could find themselves legally responsible for the posted comments of their users. Obviously, when you removing that IP Tracking, you become legally responsible for those posted comments since they are posted on your website. It's akin to being an accessory to a crime, meaning you could face the same charges.
Here in the United States, website operators are required by law to cooperate with law enforcement agencies. In the event that they don't the courts will interced or your webhost will intercede by shutting down your website and providing all pertinent information to the police of federal authorities.
You need to be mindful of the laws of your country. If you host your website in a country that has laws against posting certain things, then you, as the owner can be held liable.
