We hope this framework will guide an HCI research agenda on this impactful new class of social media system. Check out the full paper here: www.arxiv.org/abs/2509.15434

We develop a framework composed of three parts:

1. A theoretical model to conceptualize and define CCS.
2. A design space encompassing six key aspects of CCS.
3. Key normative implications of different CCS design and implementation choices.

New preprint! Crowdsourced Context Systems (CCS) like X's and Meta's Community Notes are popping up on various social media platforms. How can we better understand, critique, and design such systems?

2. "There Has To Be a Lot That We're Missing": Moderating AI-Generated Content on Reddit (CSCW25): an interview study with subreddit moderators about their experiences moderating AI-generated content

I'll be discussing two recent Reddit studies:
1. AI Rules? Characterizing Reddit Community Policies Towards AI-Generated Content (CHI24): a large-scale data collection and analysis of subreddit community rules governing the use of AI (check out the dataset!):
dl.acm.org/doi/full/10....

I'm at Seattle 4S! I'll be part of the "Risks of 'Social Model Collapse' in the Face of Scientific and Technological Advances" panel Friday morning, discussing online community governance of AI-generated content. Would love to meet others studying AI's impact on the info ecosystem!
#STS #4S

It was a pleasure to present our (@jennahgosciak.bsky.social @tungdnguyen.bsky.social @informor.bsky.social) large-scale study of Reddit community's AI rules in the AI Ethics and Concerns session at #CHI25! The paper is now available open access in the ACM library: dl.acm.org/doi/10.1145/....

An important topic of discussion in today's workshop on Sociotechnical AI Governance!

One line of the recent CMV moderator statement stuck out to me: "Our sub is a decidedly human space that rejects undisclosed AI as a core value." It's important to support community autonomy towards AI. I'm at #CHI25 presenting work on this topic and would love to talk to others doing similar work.

I also want to point to my recent paper (forthcoming at CSCW25) about moderating AI-generated content on Reddit. I spoke to CMV mods about their experiences with, and stances towards AI, in their communities. It's not a surprise that this use of AI is unwelcome!

Thankful for @sarahagilbert.bsky.social's thoughtful words on the ethics issues here: a must read for all researching online communities.

@informor.bsky.social @jennahgosciak.bsky.social @tungdnguyen.bsky.social

We look forward to presenting this work next month at CHI25 in Yokohama! Please spread the word about the dataset and let us know what cool things you use it for! fin/

We've published our data to support future research. While our study focuses on *AI* governance, this dataset of online community rules and metadata (the largest of its kind!) can be used to answer a variety of other questions about online community self-governance: github.com/sTechLab/AIR... 4/

See our paper for further details and implications for both platform designers and communities: arxiv.org/abs/2410.11698 3/

We find that a significant number of communities have enacted rules about AIGC, and this number is growing over time. These rules often focus on AI images and are most common in larger and Art-focused subreddits. Rules often evoke, as justification, concerns about quality and authenticity. 2/

*NEW DATASET AND PAPER* (CHI2025): How are online communities responding to AI-generated content (AIGC)? We study this by collecting and analyzing the public rules of 300,000+ subreddits in 2023 and 2024. 1/

We offer a novel taxonomy of AI rule types and plan to make our datasets public after peer-review. Check out the preprint (w/ co-authors @Mor, Jennah and Tung) for more details about our findings and their implications: arxiv.org/abs/2410.11698 /fin

Rules about AI most often focus on regulating the use of AI images and raise as justification concerns about quality and authenticity. /3

The number of subreddits with AI rules has nearly doubled over the last 12 months. Larger subreddits, as well as those devoted to art and celebrity topics, are the most likely to have such rules. /2

*NEW PAPER* How are online communities adapting to the presence of AI-generated content (AIGC)? To answer this question we collected the community rules for 300,000 public subreddits and identified rules governing the use of AI. /1
