In both of those cases the forum operator and ISP were one and the same. The cause for concern then is that the ISP regulated user submitted content and thus was found liable for content published because the inference is that the ISP implicitly blessed such content by not removing it in the course of their moderation. This is not a risk to ISPs today or content transmission generally. The web, as it exists today in common practice, is no different than an offline magazine publishing user submitted content because editorial discretion is applied and the magazine is well isolated from the transmission mechanism, such as postal delivery.
