SE Nuke - Listings Removed

Hi,

I noticed that after running SE Nuke, I dominate the SERPS. After a few days, it seems that my sites (such as hubpages, etc.) move down pretty far in the rankings. Why does this happen, and is there a way to prevent this?

Thanks

Dude, you already posted here http://www.blackhatworld.com/blackhat-seo/white-hat-seo/32312-se-nuke-listings-removed.html

Why are you starting multiple threads with the same question?
