Excluding existing archiving sites, do you have an expectation or think that data stored on lemmy should be permanent? E.g last 20+ years. Would it matter if old inactive content was culled? If you had the ability to export data if a sever was due to go down, what would you actually do with it.
All the comments and posts I make at a website are generalized and meant to be publicly viewable, I prefer data permanence.
