but how come he clicked on link ads on Google search?
Using a new device (not their usual one) encourages users to perform quick searches and then impulsively click on the first result. This isn't a new story for Google and its users. What's even more distressing is that their constantly improving algorithms aren't even capable of filtering out fake services.
You should know that as google is improving their algorithms to detect and filter fake services, that is also how scammers are using different techniques to deceive people to click on those ads so the best in just to avoid clicking on them completely to avoid situations like this. I wonder why someone who has about $400k will click on a Uniswap Google ads when they know that it can be a phishing link.
