Beyond the hashtag: Circumventing content moderation on social media
Social media companies make important decisions about what counts as “problematic” content and how they will remove it. Some choose to moderate hashtags, blocking the results for certain tag searches and issuing public service announcements (PSAs) when users search for troubling terms. The hashtag has thus become an indicator of where problematic content can be found, but this has produced limited understandings of how such content actually circulates. Using pro-eating disorder (pro-ED) communities as a case study, this article explores the practices of circumventing hashtag moderation in online pro-ED communities. It shows how (1) untagged pro-ED content can be found without using the hashtag as a search mechanism; (2) users are evading hashtag and other forms of platform policing, devising signals to identify themselves as “pro-ED”; and (3) platforms’ recommendation systems recirculate pro-ED content, revealing the limitations of hashtag logics in social media content moderation.

Lol no worries I think at least a few very basic functions of feeds could be simply improved if there was an innate way to treat individual hashtags as feeds, or if beside feeds people could also create collections of manually saved posts (cause some people use feeds to organize their own posts)
Anyone know any #atproto or bsky services that can 1) aggregate posts with specific hashtags or from specific users, 2) that update every few seconds or at some specifiable interval, 3) that tiles nicely if one were to project it onto a wall? LMK ⬇️ Asking for a friend! It's me! I'm your friend! :D
