What does ScrapeBox do?

I am interested in buying ScrapeBox.
But I did not understand what this Tool does? Do you can get high PR backlinks with this tool?
For 97$ it is low priced, against XRumer for 540$.

What to do with those ScrapeBox Linklists you find on BHW?

Can you recommend this software?
I think for my sites I don't need LOTS of Backlinks but HIGH QUALITY Backlinks.

Regards

Is this a serious thread? Theres a huge thread on the tool. Read it and re-read it and you will understand what it does
