Always try to leave relevant quality blog comments, but my question is.. How can Google verify this? The link is a link, let's say it's wordpress platform, the link will be in the username field, totally separate from the comment area. I just can't see how Google could rate this since the link isn't in the article/comment text.. Your thoughts? Do you think it really matters or is it just being respectful and having ethics.. I could see the same comments pulling a RED flag ASAP if your link/comment is the same over and over, but if it's just a quick, thanks, great post, wonderful, liked this, etc. the diversity is so huge.
