Backlinking my backlinks using scrapebox.

Hi,
I am hoping for some advice.
I have a bunch of article backlinks from AMR blasts and Digi-article-blaster.
I want to build backlinks to them to help getting them indexed.

My idea is to run a scrapebox autoapprove blast and then ping/rss etc.

I have loaded my urls into the 'websites' in SB commenter, and there are probably about 500 per file (I am doing smaller runs once every couple of days) and when I run the fast poster, they all failed.
I can't work out why as I only just checked that the pages were still alive using SB.

(Also, with wordpress, I have noticed greater success if I put the backlink with anchor text in the comment and just use a normal name in the name field.
Whereas, if I post to Blogengine, it works the opposite. I have found many posted comments that don't display a link, just the html, so the link works better with the keywords in the name field. Do you guys reckon that is normal?)

Any thoughts on the best way to do what I am thinking of?

Sounds like a good approach, and makes sense with the WordPress with real names. Looks a lot more legit to webmasters imo, not too experienced with the blogengine stuff though so I can't comment.

What type of backlinks are you backlinking? Web 2.0 links and link wheel type stuff?

At the moment I am working on all my article backlinks.
I also have to work on some profiles at some point. I was thinking of the same approach.

I have just worked out why I was getting failures. The pa geswere certainly alive, but comments were closed on all of them. I saw this using the slow poster.
I guess even autoapprove spamm blogs catch on eventually lol.
