Hello, I am looking to purchase Scrapebox so i can do my tier 2 blasting. I've the following questions: 1. After purchasing, do i simply open the software and click on that button to blast? 2. If i need to provide URLs, where do i go to find them? 3. Do i need to pay more money for captchas? Basically, how much does it take for using this software per month based on 10 sites?
