Someone said that buying high PR links is useless! Is that true? I have a new website with PR0 and I would like to get to PR3. I was thinking of buying like 50 links from PR4 sites. Would that help? If you say NO - why not? If yes - that would be great. From what I know, if you get 30 PR4 links to your site, you will get PR3 in matter of 1 month time. Is that correct?
