50,000 backlinks is a lot.....I'm not sure, maybe an xrumer blast can give you 50,000?
I want to build 50.000 links for a new domain, I know that I should start slow but how fast can I do it without getting sand boxed?
My goal is to build 500.000 links for this site
I need 50k to compete with a news site, I won't get banned if I do it gradually
With Ultimate Wordpress comment submitter and creative scraping....I can build 50,000 links that will show in yahoo site explorer in a week or so easily, although many of which would be no-follow....but I wouldn't risk it.... it's not really the point either. There isn't any point in building crap loads of links if you don't target keywords in the anchor. Mass links alone...even if they don't get you banned have little value if they are untargeted.
