It's a very good tool, especially considering the price. It's worth the $60 even just to use it as a proxy harvester/checker

Of course, don't expect it to do the work by itself. You need to know how to use it. But if you do know, it will help you.
What I suggest is that you understand what it can do, play with the trial version and get intimate with it. Read the numerous posts around here. Think how it fits in your SEO strategy. If after that you're still unsure if it is a tool you need, then it probably won't help you as you don't know what to do with it.
SEO is like digging a hole in the ground. In order to know what tools you need, you have to know what kind of hole you need and where you need to dig it. Is it a deep hole, a large hole, a long but narrow ditch? Is the ground hard, muddy or is it sandy? Is it more efficient or cheaper to hire a few guys with shovels, or do you need a bulldozer to get the job done? Do you need a bulldozer as well as a shovel? Maybe a jackhammer? Do you start the work with the bulldozer, the shovel or with the jackhammer? Wait! What about some dynamite? No... that is to expensive and dangerous. There are houses around and kids playing. Just so you know, XRumer is a bit like dynamite.
So the question is not if scrapebox is good, but what you want to do. ScrapeBox is good as in it does what it says on the package. Whether it will help you rank #1 in Google is however a question about your skills not ScrapeBox. I can tell you as a fact that even for those that know well how to use ScrapeBox, this tool offers an advantage only to a certain point. Then that person's skills start to limit them. If they can't code to build their own scripts to complement ScrapeBox, it only takes them to a certain point. If they know how to code and are a bit smart/tenacious, like I am (and modest might I add :lol

, ScrapeBox is just a tool that covers a part of the problem so they don't have to code it themselves and can just buy it and concentrate on the rest.
Regarding what you said about ScrapeBox being ineffective because the blogs are nofollow... it all comes to your skills. I was able to find over 500 **************** blogs, some with ScrapeBox some using other techniques. Those found with scrapebox were initially a list of over 30,000 URLs that I cut down to about 3,000 unique domains, that I then cut down to about 300 **************** blogs using my "Code-Fu" skills. Now all I have to do is "HardWork-Fu" - manual posting - which is not that fun as Script-Fu. So you see, while this is not a general rule, sometimes it is not the tool that is limited. It is the user.
All I can do is wish you the best of luck. Remember that if it's frustrating :frusty: it means you're on the right path. You just have to keep walking no matter what (insert Johnnie Walker logo here).
