Hey OP, are you covered by the GDPR or CCPA?
If so perhaps you could ask for a copy of your data that lemmy world has on your former accounts, and report to the regulator if they ignore your request. Not sure if federation helps or hurts - like could you say that lemmy world must have something of your data since other federated servers still have a copy of your content?
Would be nice if there was a way to use the GDPR here to bring some addtional accountability to the lemmy world admins.
Not sure, but account deletion is a manual process here. I suspect what actually happens is that the magazine is tranferred to the default owner / first admin account. On kbin.social that would be ernest.
See for example https://kbin.social/m/trans - a sub with few threads. I think the original owner successfully requested account deletion which is why that sub is owned by ernest now.

Not sure of the historical average time. It’s a manual process though so it will take some time for the admins to get to it.
I saw an example of this some months ago. It seems like the posts do get nuked, though with recent updates I’m not 100% certain that this is still the case. Again see /m/trans - most likely it was one of those subs where most of the threads were started by the owner posting, so when the owner’s account was deleted, so to did those threads and posts.
Actually it’s worse than this - as the entire thread is gone, including other commenters’ replies.
