I know the main idea is to avoid get penalties on money site for buffer purposes but aren't you just creating traffic/backlinks for the web2.0 places rather than your own thus wasting time with the backlinking? And worse won't these sites be ranking above your own for the same keywords if you were using the same ones in the serps? I am reading http://www.blackhatworld.com/blackhat-seo/black-hat-seo-tools/175845-scrapebox-best-practices-enough-enough-3.html (near end of page 2 I think the relevant posts are) thread and a few people have raised the issue which is what drew me to write a thread about it and noone seems to have answered it conclusively there thusfar. So what's the deal? Won't you just be boosting the web2.0's up- I don't see how the linkjuice would pass over to your money site?
