Fediverse
[12] A 2023 study by the Stanford Internet Observatory's Cyber Policy Center found that, out of approximately 325,000 Fediverse posts analyzed over a two-day period, 112 were detected as instances of known child sexual abuse material (CSAM); 554 were detected as containing sexually explicit media alongside keywords associated with child sexual exploitation; 713 contained media alongside the top twenty CSAM-related hashtags on the Fediverse; and 1,217 contained text relating to distribution of CSAM or child grooming.
The study additionally noted that, during a test run of its analysis pipeline, detection of its first instance of known CSAM occurred within approximately five minutes of runtime.
The Stanford Internet Observatory proposes development of distributable blocklists similar to BlueSky's functionality; mechanisms for pluggable hash matching and content classification (the same technology used by PhotoDNA); moderator tools such as grayscaling and blurring for certain report categories, as well as basic user fingerprinting; support and administrative interfaces for PhotoDNA and NCMEC CyberTipLine APIs; and a system of federated attestation of media analysis.
One of the first projects that included support for a decentralized social networking service was Laconica, a microblogging platform which implemented the OpenMicroBlogging protocol for communicating between different installations of the software.
The new protocol was designed to be useful for general activity streams and not just status updates, and replaced many of OStatus' external dependencies with JSON-LD and a REST API for its messaging and inbox systems, as well as making more use of ActivityStreams.
[19] The standard aimed to improve the interoperability between different software packages running on a wide network of servers and to succeed both the OStatus protocol and Pump.io.
[23][24] Following the acquisition of Twitter by Elon Musk in November 2022, certain major social networks, including Threads,[25][26] Tumblr and Flipboard, expressed interest in supporting the ActivityPub protocol, as a large number of users began to migrate to Mastodon, a server that supported the Fediverse and was also the most popular alternative to Twitter at the time.
As of November 2022[update], no information had been released by the company after the initial tweets by the CEO, with support for ActivityPub suspected to be on hold or cancelled.
[27][28] In 2024, the local government of the Stary Sącz municipality in Poland launched their own PeerTube instance[29] in order to de facto abolish its presence on YouTube.
[32][33] Ghost, a blogging platform and content management system, announced in April 2024 that they would be implementing Fediverse support via ActivityPub.
[38] Automattic CEO Matt Mullenweg tweeted on November 22, 2022, that Tumblr was adding support for ActivityPub interoperability, in response to a user's complaints about Mastodon's complexity.
[39] However, no further information was revealed for over a year, and was expected to be cancelled after a leaked reorganization that moved most of Tumblr's staff to other Automattic projects.
However, following a question from a TechCrunch reporter during a questionnaire about the leaked memo, he revealed that the interoperability feature was not cancelled and that there was a small team working on studying the potential of implementing the protocol.
[45] A faction of fediverse server admins, some of whom have listed their names under a pledge named "Fedipact", have expressed resistance to open federation with Threads over concerns that Meta would adopt an “embrace, extend, and extinguish" policy towards the network, or that Threads' moderation would fail to prevent the spread of abusive content targeted towards marginalized communities.
