Hey guys, I just wanted to confirm, is there a chance of being sand boxed by the big G if I get too many backlinks in a certain period of time (lets say 150k in one month)? I'm asking because of of the Xrumer software that can get a ton of backlinks, super quick! To my analysis, it works. Because my competitors use it and they get top rankings for very competitive keywords. I'm wondering what you guys think, and if you have experience on the matter, by all means post!
