Yes, I have seen this news since last night and I thought this was just a mistake by part of Google and they will terminate these advertising contracts soon. But it is unexpected that now when searching Metamask, in the first section, there is still another scam site called Maskmefa.io
During this period of time, when Google has not yet spoken up about this incident, we should be very careful in searching on Google. Or we can use another browser like Brave, Opera or Firefox to keep our assets and information safe.
There are many search engines: Google, DuckDuckGo (with Tor browser), Bing, etc. and you don't must bind yourself to Google if you want to search for something. Google own a big search engine but they are greed and want use it for selling their Ads (just to get money). They don't care of their users (safety, security, and financial issues).
With some crypto sites (exchanges, wallets, marketcaps) you can be safer if you remember their domain names. If you have bad memory, please save their domain names to your sheet or bookmark them on the browser you are using every day.
We should learn to avoid ad links because they aren't official link to a website or items
Save domain names and only visit to official sites to get wallets, extensions, upgrades. Don't search if you need upgrades.
While using Google search engine we need to be careful with any search results that starts with Ad- it means that it's an ad link which might be fake, malicious or real, I don't want to give a try to find out because scammers are capable of anything today
It is quite a big surprise to see this problem has never been taken into serious consideration by Google. It is their platform, their engine and you can set up a strong filter to prevent those malicious ads.
