Selling hardlinks is not allowed.
And why would someone buy hardlinks if he can get ONE WAY free hardlinks in a lot of sites. I have a list of over 100 dump links where I put my links for free and get google backlinks for free.
I am indignated to see the things some people do to make money. And I am even more surprised seeing people actually paying and giving away their money like this. 90% of these backlinks won't work anyway. Looks like a lot of people need to read more.
