scrapeboxservers (one word)
Nothing wrong with blog links as long as you don't make too many of them.
Sort and sift by PR, use the ones that are rarely linked from (require slow poster and captcha and have page rank) have a bang on topic and EXTREME heavy spun (but still readable) comment, and use to post a few dozen MAX to every inner page
Consider a ration of about 5-1 for success after moderation. So 100 "Successfully posted" will likely mean "20 Actually published"
DO NOT USE AUTO APPROVE LISTS... for this tactic.
You post and link will likely be on page 7 of a blog roll surrounded by "Buy your v!agra here" and "Romanian girl looking for a man like you in your area" crap links.
Use scrapebox THE EXACT OPPOSITE WAY EVERYONE ELSE HERE DOES.
Pick the "Captcha solve" required "None auto approve" and "Slow poster only" links.
Link to inner URL's of your blog rather than the main URL
The exact ratio of successful publish against succesful submission is something you'll have to work out yourself and will depend on your list, you posting method, your niche and your comment quality - If you have a blog with say 50 inner URL's then a good tested and filtered list of 5000 split between them all should give you decent results.
Again - DO THE EXACT OPPOSITE OF THE "SPAM" TECHNIQUES THAT ARE POSTED HERE.
Loading in a 200,000 auto approve list and pressing go will likely get you no where in the long run and a 6-12 week slappage in the short run. That's not the way to use SB - and I feel like headbutting my monitor every time I see some "numb nuts" recommend it. That sort of carnage should be saved for selling on crappy Fiverr gigs and then only selling it to people you don't really like.
As for other tools mentioned here..
google "scrapejet vs nohandsseo" and I'm pretty certain you'll find a case study of the two side by side (ahem)
Good luck
