okay look
#mastodev, there needs to be a brainstorm on something:
a lot of users are concerned about cross-instance users using their username and impersonating them

what would be a good and userfriendly way to fix this?
gnu social doesn't even have a fix for this yet, it seems, so...

@b Could someone please make an effort to explain to me the source of the concern? I have a couple of theories, but I want to start with the whole of the problem in my head.

Start with: how is this different from caring whether someone has a similar email address to yours, but at a different domain?

@HedgeMage @b Doesn't matter if it is technologically similar, Mastodon is perceived as being one universe (or federation) and if you're just viewing the Fed Timeline, you are not necessarily paying attention to which instance that user is a member of. Therefore, some could create an account with the same name and same avatar as you on another instance, but it isn't actually you and you could be blamed for things you didn't actually post. Email is a terrible analogy.
