Linkbuilding with SB but no backlinks so far

I'm working on several micro niches and it has come to my notice that my most important site isn't getting any backlinks by spamming with scrapebox.

It fluctuates between #5 and #2 in google but the backlink checker doesn't give any change in backlinks.

In all my other micro niches I see a clear increase in backlinks when I spam with sb. But this particular micro niche is stuck at 8 backlinks.
And none of the sb blogs have come through.

Any theories why?
thanks

I hav had a simular problem.Not so sure there being indexed!!! Or even blinking...
?

Did you get some links from BHW, got the proxies and blasted 'em? Or did you try searching and reading the guides at BHW?

I do something that would be considered blasting.
But the thing is I never ping the submitted links. So it would look more natural to google.

I am posting blog engine only with my lists. Happens slowly btu, the link is do follow and not so often considered for spam

Are you using scrapebox to blast your main website? Or did you setup web 2.0 properties that you blast scrapebox lists too and then have each property link to your money site?

How long has it been since you blasted? You need to give us more details for us to answer your questions correctly.
