Help me get better in scrapebox

I tried everything but I don't really see any success with SB.

1. I was using private proxies, am using free proxies now
2. I tried getting backlinks one site at once and 20 sites at once.
3. I am commenting on targeted blogs with good spinned comments.

Those of you who are successful with scrapebox:
1. How many proxies are you using? Free or paid? I saw 90% of the free proxies are blacklisted by akismet
2. How do you find those do follow sites as most of them are nofollow.
3. How many sites to you comment on in one day?

I find it very hard to get do follow blogs. For some reason almost none of my comments get approved.

What am I missing?

I'm also having the same output with scrapebox, could someone more experienced help us???

1. Use public proxies for scraping, private proxies for posting.
2. One way would be to use the do follow checker addon. It's very slow but you can run it on another scrapebox instance at the same time you're blasting other blogs.
3. You are posting on way to few blogs. Either pick out the posts with highest PR and post comments manually, or post on 100s or even 1000s of blogs at once (even if your comments are targeted).

how many proxies are you guys using when posting to thousands of blogs?

Search forum for video tutorials. There are some very good that will show you step by step what to do.

I always usually choose the least obtrusive keyword to be my name/anchor text because this adds to the chance that the comment will be approved.
