There's a mass systematic bulldozing/demolition of whole lower/working class neighborhoods happening in Jeddah, Saudi Arabia right now. Locals use Twitter spaces extensively to discuss, organize and share stories. Twitter spaces needs to have a way to join in in discussions anonymously to say the least. Please give users options around their own risk profile - including voice modulation.
This might be an annoying bug, but I wouldn't call this a doxxing vulnerability. Your userid stays the same, no matter what your handle is. Of course, the userid is mostly hidden for the end user, but there are a few services that track changing handles by referencing the userid. So you could be doxxed all the time anyways. Now it is just a bit more obvious.
Not at all the same issue but vaguely relevant — I like the idea of ambiently joining some Twitter spaces without feeling obliged to contribute.<p>Would strike me as a decent trade off that non contributors should be able to join anonymously.<p>Whenever I’ve joined something in my specific area to date, I’m called on to contribute maybe half the time by the host - which is generally fine and I’m happy to, but sometimes you’re not able to… so it puts you off joining altogether.
I love that there's a third-party collecting Twitter bugs (one of the replies in the linked Tweet):<p><a href="https://github.com/simonsarris/Twitter-Bugs" rel="nofollow">https://github.com/simonsarris/Twitter-Bugs</a><p>Twitter sure as hell doesn't pay attention to bug reports filed by their own users. You want to test this assumption? Tell me how you're supposed to open a bug report as a user.
I recently came across this while searching for some old discussions / retweets and found a tweet by someone who I know changed their handle; after clicking RT/QT/reply (don't remember) somewhere in the thread, I saw a form to reply to both their old and new handle.
