Could have happened to anyone! I am happy for you that something protected you.
There was an imbalance between:
What does the famous YouTuber get and what do i get in return?
Maybe the social engineering part was the thought to connect closer to this famous Youtuber? Which obviously is a sexy, emotional thought.
Maybe its a reminder to always check-in with oneself and ask: whats my intention and what feeling is behind it?
Maybe thats what saved you…
