I enjoy deleting my old posts and comments, but it’s lot of work doing it individually, especially with comments. For other platforms there are apps you can login with, then delete old or all content, but I can’t find one for Lemmy. Does such a thing even exist?
If I’m linking to a personal blog or something that may not have long legs I sometimes take a snapshot on web.archive.org.
I still link to the site directly so they get the traffic and visitors get any updates they might make but I know that if the direct link dies the page, as it was then, is still available for anyone who looks it up.
