Relevancy vs Quality of the website in blog commenting

[andzon]

For example, I would like to comment on a do follow blog with my link inserted in the comment. The blog post is relevant with the link i inserted however there are too many spammy links on the comment. Will this affect my website in terms of "link neighborhood" even my site is relevant to the blog?

how do you judge whether the blog is worth commenting and putting your link on it?

Does link building on blog comments actually hurt the page rank of websites if it go wrong such as spammy sites?

I agree with Keri, but would add that from a purely technical perspective you'd be best to avoid getting links from pages where a lot of poor-quality links have been left already, either by the person who wrote the blog post or by other commenters. There's reason to believe that "bad neighbourhoods" are best avoided in order to not draw comparisons between your site and spam. Sometimes you'll be naturally linked to by a page or blog that also links to poor-quality content; this isn't a huge problem in an of itself, but there's no need to encourage it.

Would you want to comment there if the link was not included, or if it had a nofollow attribute? Did you find the post because it was a relevant post, or was it found with a search query that was looking specifically for posts to comment on?

Those are a couple of questions to ask yourself as to whether you'd want to leave a link. If there are a bunch of spammy links, I'd probably avoid it myself, but that's my personal opinion.
