Here you can share your knowledge, ask questions, and engage in discussions on topics such as the benefits and challenges of decentralized social media, new and existing federated platforms, and more. From the latest developments and trends to ethical considerations and the future of federated social media, this category covers a wide range of topics related to the Fediverse.
Not sure about peertube or pixelfed, but I am sending this post from Mastodon, so depending on the situation you can.
Because mastodon and kbin are both instances of the same tools (forum/microblogging)
It's not the fediverse's job to do that any more than it is HTTP's job to make sure that the person posting on Instagram and the person posting on TikTok are the same person.
Individual instances can choose whether or not to implement identity verification.
And yeah, I can "try" to impersonate you, just like I could with email. I could spin up a cheap domain and make an email address PabloDiscobar@impersonatePabloDiscobar.site .
I would like to see folks from outside of the instance more clearly marked with where they came from, though.
No. You have to make an account for each tool. The federation part comes in that I can follow a bookwyrm account on mastodon and get reading updates. But if I want to post books I'm reading, I'll need to go make an account.
