I've migrated my #Mastodon account twice. It was not a very complex process, and took me less than half an hour each time. And I took almost all of my followers with me automatically.

And if you are on Mastodon.social, I recommend that you should consider migrating your account, too. I don't have anything personally against that instance, mind you. But it is _bad_ for the #Fediverse if there is any instance that has become "too big to block". If the moderators struggle with keeping out bad actors - and I've heard that there is a problem with that over there - then admins of other instances have to face the difficult choice of either tolerating an instance with bad actors, or cutting off their own users from a huge chunk of the people they are connected with.

And each instance has their own safety needs. I mean, I wouldn't want the strict enforcement of, say, Mastodon.art for my own instance, but I understand and can appreciate why their admins act as they do.

If you want to see the dangers of a "top-heavy" Fediverse, just look to #Bluesky . In theory, they are a federated system. But in practice, the vast majority of all users are concentrated on one system with one set of moderators so that their moderation sets the tone for Bluesky in its entirety - and their users have little choices but to accept that.

On the Fediverse, we have the chance to avoid that. And the more spread out the user base is, the better will the moderation be - it keeps everyone honest if users can easily leave to a different instance with better moderation.

An unofficial guide to using Mastodon and the Fediverse

@juergen_hubert what do you mean "block"? Are there some admins, of other instances, that want to blanket block mastodon.social because of some "bad actors" on mastodon.social?

@dtwx

It has happened before - for instance, Mastodon.art once blocked Mastodon.social. I was on Mastodon.social at the time, and noticed that I had lost a bunch of my followers.

@juergen_hubert individual users on an instance can't mute posts from an entire server? It has to be blocked by the instance their account is on?

@dtwx

They can, but the admin of Mastodon.art made the decision to defederate the entirety of Mastodon.social. Thus, all connections between the two instances was severed.

@juergen_hubert that was a weird thing to do. Thanks for explaining!
@dtwx @juergen_hubert AFAIK there's actually plenty of instances that do exactly that… (probably not major ones, but still)

@juergen_hubert
I think Bluesky isn't federated at all. It's merely distributed. One nasty person could control Bluesky next week.

Yes, I found it simple to migrate. The server/instance I was on is closing in October 2025.

@juergen_hubert This part of the Fediverse has always confused me.

I get the system-wide benefits of a decentralization, and preventing any one node from becoming too big.

But in practical terms, what does it matter for me (as an end-user) what node I'm on? I still follow who I follow, I still block bots & assholes, I still see what I see.

So why migrate?

Closely-related question ... If I do migrate, why choose one node over another? In practical terms, how does it affect what I see day-to-day?

@juergen_hubert I assume my questions fall under "Moving to a server where the community and/or rules fit your needs better" ... but I don't see how my "server" and my "community" are related, most people I follow are on different nodes anyways.

Maybe I'm doing it wrong? ¯\_(ツ)_/¯

@zenkat

The last time I moved, my needs for a new server were:

- Regularly updates the Mastodon software
- Has a character limit of more than 1,000 for posts.

@juergen_hubert But those are features, and relatively minor ones at that. Where does community fit in? Does my server affect who I see and interact with? That's the biggest determinant of my fedi experience.

@zenkat

Well, thematic fits are great, too - my previous instance, thefolklore.cafe, was excellent for my primary theme (i.e. German folklore).

Alas, the instance is stuck at a perpetual Mastodon v4.1.2, and the admin made clear that he was not able to find the time to do anything about that. So I figured it was time to move.

@juergen_hubert Can you talk more about how the "thematic" connection affects the content you see, or the connections you make?

I'm on sfba.social. AFAICT, that has little bearing on what I see in my feeds day-to-day. Would my life be any different on furry.engineer or freeradical.zone?

I always kinda felt like server instances should have a bit of the flavor of a subreddit, connecting you to like-minded folks, but maybe that's just not how it works?

(Not trying to be a pest here, this is something I've never quite understood about Mastodon and you seem like someone who knows what's up. Happy to read docs if you point me in the right direction. Thx!)

@zenkat

Well, that depends on how much you use the "Local" timeline of your instance. I don't usually bother with it, but if there are a lot of like-minded people on your instance, it might be worth checking out!

@zenkat @juergen_hubert There are some limitations. A big one I didn't notice at first is that you can only search posts known to your server. https://lucahammer.com/2024/04/25/mastodon-advanced-search-guide-and-operators

@juergen_hubert
The moderators of mastodon.art - a quite categorical name - took over photog.social - a very categorical name - and began blocking and making it over in their own image.

I noted that I followed enough people from mastodon.social that this would be a nuisance, and migrated. But a new photography instance is needed.

I'm unconvinced, as in would like an equation with numbers, that spreading th3 bad actor and moderation problem among more small instances reduces it for others.

@juergen_hubert
Erosion is one approach, do we know how trickling away Vs newly joining moves size?

Recruiting is a sub-class of that - make an instance designed for 10 000 mastodon.social users, tell them in waves, see them move.

Fission is a more obvious approach, where at some size the members of big instance.maybe suddenly find they are either members of biginstance1.maybe or biginstance2.maybe

You'll have to do something mildly clever with the admins of course.

@juergen_hubert

Being on "an instance too big to block" is the only defense against Fedi drama and against losing your old posts when you are forced to migrate due to server owner burnout.

@juergen_hubert when you migrate your account to another server, what happens to your history?

@juergen_hubert 1. It's irresponsible to encourage account migration without mentioning that you lose all your posts

2. Bluesky's problem isn't that it has one oversized "flagship instance", or even close to that. It is that the whole thing is only theoretically decentralised, because the only way to run an "instance" is to mirror everything ever, and there's no benefit in return for the commitment of resources
