Automatically posted comments (using Blog Comment Poster/Comment Poster/YouTube Comments Poster tools) or trackback messages (using Trackback Submitter Tool) are identical to thousands of other comments posted on the Internet. These messages have properly formatted author's name or nickname, a valid backlink to any of your sites (if enabled via software settings section) and comments text written by you and customized to meet website content (if software supported variables are used).
To keep it short, the software does not add any extra tags or footprints, so automatically posted comment will be the same as manually posted comment.
