We were taught to write negative reviews on these kinds of schemes on a blogging course I took. It's a good way to bring attention to a legitimate project.

This is an interesting way to do marketing, I never thought about this.

You could include an affiliate link after your warning and people will still sign up for the scam. Is that immoral? Idk. They're bent on throwing money away. I would put that money to better use than the ones running the scam in most cases. But to earn off friends, classmates, or family is taking it too far. They'll come back and blame you even though you warned them. Not smart.

I just think if people know it's a scam, know they are being scammed, and they are participating in a scam, they are entitled to the consequences that comes with awareness. I'm even having trouble convincing my folks that a certain app they installed is a scam right now. They would rather invest in a scam than invest in Crypto. I don't blame them entirely because they didn't invest more time learning financial literacy like I did, I'll just put more effort convincing them and let them learn if they choose to be stubborn.

Thank you for your inputs :D
