Search engines want natural links. If you get too many links too quick, they can tell it is not natural because links are not suppose to be that easy to get. Also factor in the issue of quality v.s quantity. It doesn't matter if you have 10 or 10,000 links. If they are irrelevant to your site, and have low PR's, you will be pushed down the SERP's. Also links with the same anchor texts will get you in trouble. You can get 10 relevant and authoritative back links, and they will boost you even higher than all 10,000 you get if they are not authoritative. Anymore help get better rankings with SEO Services Plus. Although 10,000 links are plenty, I would not recommend it, but it has its advantages if it correlates with a good strategy which is more advanced for here. Good luck.
