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.
Data permanence has to be important, because of what people have already said about usefulness. But, well, I don’t know if this is possible, but I think old posts have to be blocked for new votes and comments. Maybe 6 months old or 1 year old.
