Would you consider making something for deleting past content? I was talking to someone recently about how they want to remove most of the old content, but they want to leave up certain things. That feels somewhat similar to the actions they would take here, so it might be a cool feature to have. Maybe even "see what subreddits I've posted in, and pick what to delete"
Also, would you care to add your Lemmy and other fediverse accounts to your website? ;)
