In terms of privacy reddit has it better(still bad but better than Lemmy) because your content is locked behind a paywall only few companies can access. On the other hand, any one can train their AI on Lemmy posts and access all history of all users freely. The difference is that on lemmy only the companies that collect your data profit, while on reddit also the owners of the platform (reddit itself) profit.
No, it’s just open free for the taking by anyone who decides to spin up their own instance, or to anyone who decides to scrape from an instance frederated with yours without robots.txt set against web scrapers. Hosters could even intentionally break federation to prevent deletions from syncing.
I love lemmy, but privacy is not one of its features.
Any script kiddie can scrape the entirety of Lemmy, with the exception of direct/private messages. robots.txt is merely a request, with no enforcement capability.
