Ok, this might be a dumb question, but is it really technically possible in any way - even a convoluted one, like manually downloading HTML pages from Facebook? - to mass import posts from one’s Facebook into Mastodon or Friendica instead of painstakingly copying them one by one? I’ve got a 10+ year archive to port and it’s a daunting task to go through them…
Yeah, I was going to suggest a data export, as this will often give you a handful of files, most importantly would be a CSV containing all your posts. It would probably be relatively easy to automate the process with that file.
