What is the smartest rug pull people have fallen for?

By smart I mean that there has been a team/face behind it, some technologies revealed and projects in the making which would make the coin look like something real. But then something has happened and all the people got scammed out of their money.

Squid token for example wouldn't be a really good and thought out scam , people that invested were just clearly uninformed or caught the notion and tried to time the market for quick money.

I am relatively new to crypto and have probably missed it so I was interested in learning about it and not making the mistake as other people before me.
