The potential for accounts to vanish if the instance they started on is, to me, the single biggest hurdle that Lemmy will face with casual users. I think that the devs need to really consider figuring out a way to make user logins global.

I said this the other day, but I think it may, unironically, be one of the first times I've ever seen a genuine use for a blockchain, but I have no idea how to implement it.

The reason that the big social media companies came to exist is precisely because people didn't like having to have a dozen accounts for all their different communities. Lemmy fixes that problem through federation, which is great, but introduces a new problem of "your account could just disappear, making all your contributions vanish." I know that was technically a problem before big social media companies appeared and everyone was using forums, but it's a big plus of the current social media giants- you don't have to worry too much about the company failing so completely that the website gets shut down, which is the only way you'd lose your account, any time soon. People are used to that stability, and will not be happy if they join an instance in the fediverse only to have the rug yanked out from under them.

If we want this to be a true alternative to big social media, it needs that stability.

It was mastodon.lol. Great server early on but the admin Nathan went off the rails in a big way.

that's...really unfortunate

The old internet didn't have an all encompassing issue with bots and bad actors trying to gain your trust, a public post history is basically the closest thing a person can have to a trustable identity online, it's not a perfect solution but it helps

Some of us have friends online and we'd like to be able to do things like continue conversations while still being identifiably the same individual.

Also there's consideration of privilege schemes where the access is based on karma, activity, or account age. That's aside from the potential issues that could arise if someone with high privilege (supermod for example) has their identity vanish leaving a community minus whatever function they might have been performing (this user is allowed to send the bot commands, etc).

On a personal note, not having to jump through a bunch of hoops intended to screen out bad actors just to access a community or group where you were already a member in good standing.

Beyond that, there's some people who really want to express their particular identity or brand online - for example I sometimes write using a particular name. If I could no longer use that name and not even access my account to tell people that, it would not help my audience find me or my back catalogue.

Beyond all those things, having access to my post history means I can look back at things - have you never sat and looked at old diaries or photos from when your were a child? Or been reminded of some event you enjoyed? Or even just wanted to check something went down like you remembered it?

Because social media exists. There is identity attached to your online presence for the vast majority of people.
