I'm trying to do some research on google. I'm using specific keywords like inurl, site, etc.... But google seems to think I'm trying to do harm (actually I'm doing recon on a website for a friend)... So it displays this message
Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot
What can I do against it ? Is there an alternative to google to recon using a web crawler without being blocked ?
