Whitehat Newbie Backlink Question

So I am working with a little site trying to get my feet wet in SEO. I have been doing some manual blog commenting for backlinks and I have a question.

Two of the backlinks I got are from blogs that update everyday like ten times a day and it seems that everytime they update, for some reason I get a new backlink. So every morning I wake up and there are 20 new backlinks to my site.

At first I thought to myself that this is great, but now I wonder if this is going to hurt me. The sites may be content scrapers or just aggregating dup content.

My question is, do you think this will hurt my chances of ranking well? If so, what can I do about it?

This is nothing to be concerned about. Also keep in mind Google/Yahoo do not show you every last backlink that they have on record.

This is only temporary. These blogs that you commented on have a plugin of recent comments that is shown on every post. After other comments will push your comment down, you will be left with only a backlink from the post you commented on.

Thanks for the replies. I feel relieved now, I knew I could count on BHW.
