The part of due diligence to prevent the scammer or someone who falling the scam, that's would be better when we already expose the project it has some scam assumption before they successful gaining some money.

If we need to wait, until the project scam other people there is no reason why we doing due diligence before is investing. The purpose why we need due diligence to prevent falling to a bad project or even scam.

But sometimes we need also judge by the cover when you doing business with someone you need to prepare all thing was on good condition. Let's say when they copy-paste maybe some image or using a template for their website, maybe we still can understand that's.

But since they a copy-cat a word from other projects when the explaining of the project should be unique. If they can make it a unique description of their project, then they don't know what to do for the project itself they even cannot describe the project using their own word. How can we make sure, using the money from investor properly XD.

Just throwing my 2 satoshi bitcoin XD.
