I would like to share something with you regarding the tool which picks domain names and their respective emails by visiting one website to another. Actually, two days back I tried software for the same and after that when I searched on google, it was asking me for verification code (displayed on top of text box) to execute the search. After that google works normally.
My main concerned is to know that are these kinds of softwares are good for our website or not? Because I am using our system to run that software, is it possible for google to know that I am having xyz.com and it will banned my site because that software.
