It works. I can promise you, having done it myself over and over again, it works. So long as your domain has a bit of age and genuine authority behind it, so long as you don't go from one link a week to ten thousand links a week overnight, and so long as you continue to invest in quality content and 'clean' link building, it works
But, as a strategy, it's less effective than it used to be, and some of the smartest engineers in the world will be actively trying to block it, and you. I only touch those tools if I'm looking to rank a personal project that I won't miss too much if Google slaps me out the index - I certainly would never touch it for a client who will be concerned with their brand (read; every company ever) for example.
I assume by the nature of the question you're reasonably new to SEO? My advice is learn how to get sites to rank 'properly' first, using genuine content marketing (Seriously, setting up a network of satellite sites is no easier than getting 5 guest post spots on related blogs). That is the skill that's still going to be money for you in 5 years time, not 'How to use Scrapebox'. You can always augment that with whatever exploits exist at the time.
