When a website has been flagged by Google Safe Browsing for social engineering, that's usually the last word on whether you should engage with it. That's the situation with ffhfsh.weebly.com, which received this warning for attempting to trick visitors. No amount of technical polish can override that kind of active security alert.
Beyond that flag, this site is essentially a ghost. The domain returns a 404 error page, meaning you can't even view its intended content. There is no contact information, no about page, and no social media presence. The WHOIS records show no owner details at all. For a legitimate site, even a new one, you'd expect some way to identify the person or business behind it.
The question 'is ffhfsh.weebly.com a scam' can't be answered definitively because the site barely exists as a functioning website. But the evidence that does exist points in a concerning direction. A site that combines total anonymity with a Google safety warning has already given you the answer. Don't enter any personal information here and don't click through any links on the page.
For any new website, the safest approach is to look for clear contact information, an about page, and a history of being crawled by the Wayback Machine. This site has none of those. When you're asking 'is ffhfsh.weebly.com fake,' the real question is whether you can afford to risk finding out the hard way. You can't.
