Many beginners can't tell the difference between official and fake websites because they don't look at very similar website links, the metamask extension application doesn't update realtime to block phishing access, so you have to rely on your own abilities for personal security.
Google failed to filter out phishing site from showing up when someone did a certain search. Nothing is really safe for anyone on the internet when they fail to verify the legitimate security of the site they want to visit, this is possible with many apps on playstore as well as google extensions. Take precaution by bookmark site you use frequently, including bitcointalk.org because only then can you prevent visiting other phishing site.
