What is Scrapebox?

Scrapebox is a software for automatic blog comment posting. Most see it as spam because some of the people that own it, well, spam. Their comments are not relevant or value-added. I believe it falls under blackhat. It does other stuff besides comment posting but that is the primary purpose. It can be used to scrape virtually any kind of data from SEs. It also has other addons that make it more useful like the Rapid Indexer.
