Twitter has blocked its users from sharing some links to its social media rival Mastodon.

Mastodon is divided into groups, called servers, based on many topics including the UK, snooker, and security.
Twitter has blocked links to some of the largest servers which users would join, including the most popular “social” channel.
And Twitter is also stopping users from adding links to their Mastodon account in their bios – calling them “malware”.

There is absolutely no evidence to support the suggestion that Mastodon contains malware – malicious software that can harm your device.
Mastodon said it gained hundreds of thousands of users in November, with some Twitter users seeking alternative platforms.
A subsequent attempt to turn the reference into a clickable link to her Mastodon page cannot be posted to Twitter.

It is not clear how many Mastodon servers have been blocked on Twitter, or why.
Users attempting to post links to blocked servers will receive an error message instead, which says: “We can’t complete this request because this link has been identified by Twitter or our partners as being potentially harmful.”

As well as blocking certain links to Mastodon, Twitter has taken action against its rival’s main account.

The Twitter account @joinmastodon, which advertised the site and its features, was unexpectedly suspended on Thursday alongside those of several notable journalists covering Twitter owner Elon Musk.
This has led the EU to threaten Mr. Musk with sanctions, with commissioner Vera Jourova warning that the EU’s Digital Services Act requires respect of media freedom.

“Elon Musk should be aware of that. There are red lines. And sanctions, soon,” she tweeted.

A Twitter spokeswoman told the tech website The Verge that the journalists’ ban was related to the live sharing of location data.

This came after Mr. Musk vowed to sue the owner of a Twitter account that tracked his private jet. This account has also been suspended.
While no reason has been given for the Mastodon suspension, there is a coincidence in timing – in the few hours beforehand, @joinmastodon shared a link showing where the person tracking Mr. Musk’s jet can be found on the rival social media site.
