Netcraft toolbar effectively forms a giant neighborhood watch scheme, empowering the most alert and most expert members to defend everyone within the community against phishing frauds. Once the first recipients of a phishing attack have reported the target URL, it is blocked for community members as they subsequently access the URL. Widely disseminated attacks simply mean that the phishing attack will be reported and blocked sooner.
The toolbar also traps suspicious URLs containing characters which have no common purpose other than to deceive. It enforces display of browser navigational controls (toolbar & address bar) in all windows, to defend against pop up windows which attempt to hide the navigational controls. It also clearly displays sites' hosting location, including country, helping you to evaluate fraudulent URLs.
