I just wondered about Lemmy and post upload features…
Pixelfed is testing and releasing soon the feature for transferring all Instagram content across via account download then post upload. Calckey already has post upload for many Fediverse account types (eg I’ve downloaded then uploaded my posts from Mastodon to Calckey) and has Twitter post upload close to finished. Mastodon is building post upload too. Various other platforms working on similar.
I wondered if people should be data backing up their Reddit accounts (especially if they’re doing that Rexit fill posts with random garbage stuff) as there’s a chance in future for data upload here (or Kbin or w/ever).
Yes to recreate threading someone would have to scrape the whole data of a thread and all sorts of other issues. But authored threads with that succession of OC posts might be re-constructible. I have various threads in that progressive structure vein on Twitter that I am planning to bring across from Twitter to Calckey for example, but with microblog there is no community selection needed, which would be an extra hurdle.
