Thank you all for your valuable input.

That's correct, thank you for these additional points that support the fraud allegations against this suspicious project. Indeed, the popup may make many people connect their wallets and sign a transaction on this platform, especially since it says they need to do this "to start forging NFTs and earning Yield." So this is an essential step, and it is one of the major red flags. If the signature is for a malicious contract, it could lead to the draining of the wallet's assets.
The VirusTotal scan result is another important red flag that should not be ignored. A 1/92 detection alone does not prove that the website is malicious, but combined with the other anomalies, it certainly deserves attention.
