Hi, I see a few of the crappy scrapebox blast gigs on Fiverr offering 20.000+ links. I have a Tumblr blog which contains articles that link back to my money site. Is it a good idea, or even worth buying one of these crappy gigs and then blasting the tumblr site? To clarify, I want to buy a scrapebox blast gig and submit my tumblr 2.0 blog. Worth it? Also, when I submit an article, am I OK to just directly copy an article I've written for my blog, or do I have to spin my own content again? If anyone can answer both of those questions it would be great. Thanks in advance.
