Post Substack comment
Post a comment on a Substack post as the logged-in account. The account needs a display name set up on Substack first (via any post's comment box) — the script fails loudly with instructions if it isn't.
Delete Substack comment
Delete one of the logged-in account's own comments on a Substack post, by the post URL and the comment's id (from post_comment or get_post_comments). Only your own comments can be deleted, and this cannot be undone.
