Since Lemmy is federated, and the admins of each instance choose what’s allowed and what’s not in their own instance.
How do you feel about what’s allowed and what’s not in your current instance ?
I’ll start: I’ve read people complaining about my instance admins, but I haven’t experienced nor seen anything I specifically disagree with.
And I’ve read things they wrote that I absolutely agree with, like not federating with Meta under any circumstances.
So for now, I’m happy with it. If I get banned randomly, I don’t think I’d go to a different instance, though. I’d probably just stop visiting Lemmy altogether.
Copy settings to new account, add a note in your old profile telling people you’ve moved to another instance and add the link to your new profile. Use the same Display name in both. Done. If you want to remember what you posted, you could always search and filter by both your old account and new account. It’s effectively the same as a transfer.
