Social platforms, and the online communities that use them, are evolving at a rapid pace. As a result, research and development regarding how to moderate online communities is being out-paced. In this paper, we present a novel framework that will allow moderation researchers and practitioners to not only keep-up with the diverse landscape of available platforms and affordances, but also comprehensively represent and analyze moderation on these platforms. The MIC framework represents a social platform's moderation ecosystem using a base-set of 12 platform-level affordances, along with a notion of the inter-affordance relationships that can exist between them. These affordances fall into the three categories -- Members, Infrastructure, and Content -- that are derived from Grimmelmann's taxonomy of moderation, a framework that is already widely accepted and used by the moderation research community. To show how MIC serves as an insightful augmentation of Grimmelmann's lens, we begin by describing how its components have already been shown to impact Grimmelmann's techniques for moderation. Then, we demonstrate the advantages of using an affordance-aware framework like MIC by analyzing several social platforms over the course of two case studies. First, we analyze individual platforms using MIC and demonstrate how MIC can be used to examine the effects of platform changes on the moderation ecosystem and identify potential new challenges in moderation. Next, use MIC to systematically compare three platforms and propose potential moderation mechanisms that each can adapt. Moderation researchers and stakeholders can use such comparisons to uncover where platforms can emulate established, successful and better-studied platforms, as well as learn from the pitfalls other platforms have encountered.
