Some time ago there was dismay on Mastodon (and Pleroma ?) instances about data scraping. Before that happened there were privacy concerned people automatically deleting their own toots, limiting them for example to the latest toots for thirty days. With Lemmy things are different since Lemmy is a link aggregator rather than micro blogging, and Mastodon has boost option (Called replay with Pleroma ?). However deleting your older comments (but not posts) automatically would be really nice for privacy reasons.
It might be “easier” but is it the right thing to do? Also, as others have said, likely there is a copy of it somewhere anyways, so why bother deleting it?
You keep pushing your own agenda in this conversation without looking at my privacy concerns, and it makes me feel uncomfortable. More than before I feel like deleting my account here.
