Can blog comments hurt you?

I think your not violating any rules there as long as your not spamming and you contribute in discussion that would be more appreciated.

Blogs can hurt you if they flood your blog with spam.

I think if you provide valuable comments on the blog then it would be fine but if the comments have no relevance on the blog's topic and full of unrelated links then i think it would have negative impact on your blog.
