You could probably find some ways to get a few of em but i don't know.
You shouldn't really need more than one or two accounts tho. Talking from kbin :)
Why are people pretending this isn't an issue??? Of course it is lol.

It exposes the bigger problem with Lemmy: lack of auditing.
i think the shitcoin trend and NFT shit is over, but crypto as a technology and cryptocurrency certainly isn't. I don't see BTC, ETH, XMR dying aaanytime soon, especially the former and the latter - they're gold standard on the net already. Overengineered crypto like ETH seems to be less popular now.
The stuff listed in OP doesn't really seem like much concern. "What you put on the internet is there forever!" is completely true, and things like this should only make it more concrete that you can't rely on your service provider to delete information somebody else already archived.
With that being said, default privacy settings - at least on Kbin - seem pretty bad.
