If the comments are nofollowed then it won't make a difference. Focus your energy on links you are responsible for, links where you had a hand in selecting anchor text etc.

Agree. If the links are nofollow, they shouldn't harm you. Also, you need not add a link in each and every comment. Its good to be selfless and get no link in return of a comment. This will make your your commenting and link building activity look natural and not intentional.

If your link is in the content & in natural way, we not need to take any action but many time you see huge number of comments by automated system or comments specially used to target some particular keywords, in that case you must report such pages to google.

you can always use the Disavow in Google webmaster tools to no count those links or sites in your backlinks.

Just want to clarify that in-content links in a guest post are considered unnatural by Google.
