i made a post with my thoughts about the whole berries.space archival thing here: https://bune.city/2019/05/archive-team-and-the-fediverse/
"Just because something’s publicly available doesn’t mean people want it harvested and stored forever by a dedicated group of data archivists. Posting your phone number on a billboard isn’t consenting to having your phone number posted online by an archival team. Neither is protesting in public, or having a conversation in public, or going skinny-dipping in public, or walking past a CCTV camera in public. Being in public does not mean you automatically consent to having your activities archived."
