I mean, pretending to be someone in another instance, “stealing” the username, is trivial. I see the more likely targets being instance admins or high profile users. Should we worry somewhat about this?
That’s why instance is part of the username. It’s no different than email addresses.
Confusing similar domain names are a common thing with email. Micr0soft.com vs Microsoft.com. Same idea could be done with instances.
His concern is probably that in comments etc. only username is displayed. You have to go to person’s profile to discover their instance.
Instance is shown if it’s different to the one you’re on. I can see your instance is vlemmy.net
Not if they set a display name. Many of the mobile apps are also bad about it even without a display name.
Some other projects in the fediverse have a verification mechanism in place.
I personally like Mastodon’s: if you add on your profile a link to a webpage that itself links to your profile, Mastodon will show a green checkmark next to the link.
So you can verify your profile by linking to a webpage you own or testifies your account’s authenticity (ie. your blog, your author page of the publication your write for, etc.)
It’s a bit of a problem, indeed. Here’s a practical example of that:
In this example, I’m writing from a lemmy.ml account, but the display name impersonates another account in another instance (beehaw.org). Anyone could do this with someone else’s account.
Based on that, I think that:
- the Lemmy software should not allow you to use “@” as part of your display name. Ever. Reserve it as a special character.
- clients should always show which instance you’re from, even with a display name. A simple icon would be enough as long as instance admins set up uniquely identifiable ones.
- two accounts in the same instance should never be allowed to use the same display name.
And for us, users: never rely on the display name. If the identity of someone is contextually relevant, always check the actual username, not the display name.
Twitter implementation seems good enough. Big display name with smaller unique handle below. Might be a bit bloat, but solves the problem.
To me, this just seems like a variation of the age-old issue of online impersonation. In the early days of social media, there were people squatting on famous people’s name/registering variations.
On my instance, admins are tagged as such which seems like a good solution. I wouldn’t be surprised if we start seeing verification like on Mastodon, though I couldn’t find any issues for this on their github.

It also seems very weird that you can reply to a deleted comment! (I deleted it because what I was saying was wrong in multiple ways, not just the one you pointed out)

This was discussed deeply a few days back.
It’s something we should be worried about everywhere we go online.
So try having at least 3 different passwords for personal accounts/websites and also contact moderators or support if you suspect your account has been compromised.

That’s an awful take. Grab a password manager and have a random password for every single account of yours. That way all you have to do is remember a single strong password and that’s it. Instead of playing Russian roulette when one service you use gets hacked and someone gets a hold of your username / email and one of your 3 different passwords…

That’s terrible advice when password managers are a thing. Also, this is about impersonation, not credential theft.
Not everyone has access/knows how to use a password manager.
