Black Hat Seo

I recently purchased 10,000 wiki back links for 5 dollars, and I purchased 10,000 scrapbox back links for $10

and I purchased 66 hi pr back links for 30

Now I am getting more business then ever, but could there be a downside

all of the place where the links were place are valid.

Also I gave them an article to spin. Is there a down side or is this all pluses recently brought in 45,000 in sales in one week.
