The problem with this is trust. If you could seamlessly migrate like this, there’s nothing to stop someone faking a long post/comment on their own instance, making them look very legitimate and then migrating that account to a trusted/legitimate instance.

Then using that for spam/selling block chain etc.

People are the reason we can’t have nice things.

As I intentionally filter out as much US politics as I can, this has come out of nowhere for me.

Australia has a couple of really simple things baked into its electoral system to resist something wildly unpopular like this from getting in power:

1. Compulsory voting. These MAGA crazies are not and will never be the majority. If everyone had to vote, they’d never get in.
2. Proportional voting. We vote for multiple candidates. If our first choice doesn’t get in, our vote goes to our second choice. Then third etc. we aren’t forced to vote for a lizard just to prevent the worse lizard getting in (it still almost always comes down to two parties, though).

I know these are total non-starters for our American friends. “You can’t make me vote, that’s against the constitution or something”.
