Content Moderation on Distributed Social Media,” by Prof. Alan Rozenshtein


The article is right here; listed below are the Introduction and the beginning of Half I:

Present approaches to content material moderation usually assume the continued dominance of “walled gardens”: social-media platforms that management who can use their providers and the way. Whether or not the dialogue is about self-regulation, quasi-public regulation (e.g., Fb’s Oversight Board), authorities regulation, tort regulation (together with adjustments to Part 230), or antitrust enforcement, the idea is that the way forward for social media will stay a matter of incrementally reforming a small group of large, closed platforms. However, considered from the angle of the broader historical past of the Web, the dominance of closed platforms is an aberration. The Web initially grew round a set of open, decentralized purposes, lots of which stay central to its functioning right this moment.

Electronic mail is an instructive instance. Though e-mail is hardly with out its content-moderation points—spam, particularly, has been an ongoing downside—there may be far much less dialogue about e-mail’s content-moderation points than about social media’s. A part of it’s because e-mail lacks a few of the social options that may make social media significantly poisonous. However it is usually as a result of e-mail’s structure merely does not allow the diploma of centralized, top-down moderation that social-media platforms can carry out. If “ought” implies “can,” then “cannot” implies “needn’t.” There’s a restrict to how heated the debates round email-content moderation could be, as a result of there’s an architectural restrict to how a lot e-mail moderation is feasible. This raises the intriguing chance of what social media, and its accompanying content-moderation points, would appear to be if it too operated as a decentralized protocol.

Thankfully, we do not have to take a position, as a result of decentralized social media already exists within the type of the “Fediverse”—a portmanteau of “federation” and “universe.” Very like the decentralized infrastructure of the Web, through which the HTTP communication protocol facilitates the retrieval and interplay of webpages which might be saved on servers all over the world, Fediverse protocols energy “cases,” that are corresponding to social-media purposes and providers. A very powerful Fediverse protocol is ActivityPub, which powers the preferred Fediverse apps, notably the Twitter-like microblogging service Mastodon, which has over 1,000,000 energetic customers and continues to develop, particularly within the wake of Elon Musk’s buy of Twitter.

The significance of decentralization and open protocols is more and more acknowledged inside Silicon Valley. Twitter co-founder Jack Dorsey has launched Bluesky, a Twitter competitor constructed on the decentralized ATProtocolMeta’s Mark Zuckerberg has described his plans for an “open, interoperable metaverse” (although how far this dedication to openness will go stays to be seen). And established social media platforms are constructing in interoperability with ActivityPub purposes.

Constructing on an rising literature round decentralized social media, this temporary essay seeks to present an summary of the Fediverse, its advantages and downsides, and the way authorities motion can affect and encourage its improvement. Half I describes the Fediverse and the way it works, first distinguishing open from closed protocols after which describing the present Fediverse ecosystem. Half II seems to be on the particular challenge of content material moderation on the Fediverse, utilizing Mastodon as a case research to attract out the benefits and downsides of the federated content-moderation strategy as in comparison with the at present dominant closed-platform mannequin. Half III considers how policymakers can encourage the Fediverse by means of participation, regulation, antitrust enforcement, and legal responsibility shields.

[I.] Closed Platforms and Decentralized Options

[A.] A Temporary Historical past of the Web

A core architectural constructing block of the Web is the open protocol. A protocol is a rule that governs the transmission of knowledge. The Web consists of many such protocols, starting from people who direct how knowledge is bodily transmitted to people who govern the commonest Web purposes, like e-mail or internet searching. Crucially, all these protocols are open, in that anybody can arrange and function a router, web site, or e-mail server with no need to register with or get permission from a government. Open protocols have been key to the primary part of the Web’s development as a result of they enabled unfettered entry, eradicating limitations and bridging gaps between completely different communities. This enabled and inspired interactions between teams with varied pursuits and data, leading to immense creativity and idea-sharing.

However beginning within the mid-2000s, a brand new era of closed platforms—first Fb, YouTube, and Twitter, and later Instagram, WhatsApp, and TikTok—got here to dominate the Web habits of most customers. In the present day’s Web customers spend a median of seven hours on-line a day, and roughly 35% of that point is spent on closed social-media platforms. Though social-media platforms use the usual Web protocols to speak with their customers—from the angle of the broader Web, they simply function as large internet servers—their inner protocols are closed. There isn’t any Fb protocol that you could possibly use to run your personal Fb server and talk with different Fb customers with out Fb’s permission. Thus, main social-media platforms are a very powerful instance of the Web’s regular, two-decades-long takeover by “walled gardens.” …
