The only time I encountered this was after a power outage when my ISP's DHCP server handed me a new IP that was tainted. It felt like every major website was suddenly full of captchas.

Eventually I had to unplug the router for 24 hours until the ISP let go of my DHCP reservation. When I reconnected it gave me a new IP and the problems went away.
