You can blame Google, they show these sites as a first search result for words like wallet generator, generate bitcoin address, paper wallet, and they may also tell the user, generate the key offline to ensure that your coins are not stolen.
Google doesn't care, nor do they carry out any research whether certain sites are scams or not. It's also possible to purchase ad space and advertise scams in Google ads to other users. Remember when ChipMixer was still alive and you couldn't find the official website on Google? At the same time, there were loads of phishing sites that appeared on top of the search results. It's the same with other mixers, like Sinbad. The phishing versions aren't the first result, but they still appear close to the top.
It worth to say that I tried to visit WalletGenerator.net from popular browsers right now and all of them gave me a warning that it's a fraud website.
I haven't seen a result from those reports in years. Google doesn't care, and I gave up.
Maybe they will remove it from their search results if many people report it.
Reporting bad sites shouldn't be a petition that needs to be signed many times.
It's not a petition but is very logical that the more reports they have, the higher the chance of taking the case seriously because tons of websites are reported every day by bots and spammers for no reason, so, how can google take care of each reports if it doesn't take the number of reports in consideration?
If it was legal, it would explain to users the risks involved.
It does "explain" the risks:
To be more secure, you should download this wallet generator from your browser and run it offline.
That text was there long before the site was bought by a scammer who compromised the offline version. It also shows "We" as if it's the same owner, and endorsements from long lost times.
The scammer is very clever, played perfectly with words and the advice of generating it offline via downloaded website. By the way, problem is that even when I first typed paper wallet, my results were articles about these online paper wallet generators and now I understand that a lot of people don't do research and trust the first information that they get on Google.
