Meta just made an important update for Threads users who are sharing posts to the fediverse. The company began allowing users to opt-in to sharing their Threads posts to Mastodon and other ActivityPub-powered services back in March. But the integration has been fairly limited, with Threads users unable to view replies and most other interactions to their posts without switching over to a Mastodon client or other app.

That’s now changing. The Threads app will now be able to show replies and likes from Mastodon and other services, Meta announced. The change marks the first time Threads users who have opted into fediverse sharing will be able to see content that originated in the fediverse directly on Threads.

There are still some limitations, though. Meta says that, frustratingly, Threads users won’t be able to respond directly to replies from users in the fediverse. It also notes that “some replies may not be visible,” so Threads’ notifications still won’t be the most reliable place to track your engagement.

Meta also announced that it’s expanding the fediverse sharing options to more users, with the feature live in more than 100 countries. (Instagram chief Adam Mosseri said the company is hoping to turn the fediverse beta features on everywhere “soon.”)

The changes are an important step for anyone who cares about the future of decentralized social media. Though Meta has been somewhat slow to deliver on its promises to support ActivityPub in Threads, the app has the potential to bring tens of millions of people into the fediverse.

Snapchat is, once again, beefing up its safety features to make it harder for strangers to contact teens in the app. The company is adding new warnings about "suspicious" contacts and preemptively blocking friend requests from accounts that may be linked to scams.

It’s not the first time Snap has tried to dissuade teen users from connecting with strangers in the app. The company says the latest warnings go a step further in that the alerts rely on “new and advanced signals” that indicate an account may be tied to a scammer. Likewise, Snap says it will block friend requests sent by users who lack mutual friends with the requestee, and "a history of accessing Snapchat in locations often associated with scamming activity.” The app’s block feature is also getting an upgrade so that users who block someone will also automatically block new accounts made on the same device.

These updates, according to the company, will help address sextortion scams that often target teens across social media platforms, as well as other safety and privacy concerns. Snap, like many of its social media peers, has come under fire from lawmakers over teen safety issues, including sextortion scams and the ease with which drug dealers have been able to contact teens in the app. The latest update also just happens to come shortly after Rolling Stone published an exhaustive investigation into how Snapchat “helped fuel a teen-overdose epidemic across the country.”

The article cited specific features like Snapchat’s Snap Map, which allows users to share their current location with friends, and “quick add” suggestions, which surfaced friend recommendations. (The company began limiting “quick add” suggestions between teen and adult accounts in 2022.) And while teens can still opt-in to the Snap Map location sharing, the company says it’s simplifying these settings so they’re easier to change and surfacing more “frequent reminders” about how they are sharing their whereabouts in the app.
