I don't understand this obcession people have with ''passive income''... if you need ''active income'' and you are willing to work to earn money, there are several ways to do that, for example you can offer your services as a freelancer, or you can upgrade your account on BHW and offer automation services here or you can also create your own SAAS and promote it or you can also partner with local businesses and sell leads with your tools
But ''passive income'', I don't know, for me you need to work hard if you want to make money, the only possible ''passive income'' way that crosses my mind is creating a SAAS and charges monthly comissions for it. In this case, you work only once (to create this scraping tool) and people who needs your tool will need to keep paying it in a monthly basis.
