"This is a message to YCombinator companies and hopefuls: if you tell Facebook about your startup before you reach critical mass and you get found by Facebook in any way you're an idiot. They will steal your company's ideas and try to get you to take a small price for your company and vision and take a job at Facebook. Which by the way is going to be a job that sucks. Don't do it. It's a scam. It's a trap. It's a trap. It's a trap. Insert Star Wars quip here. It's a trap. IT'S. A. TRAP. End of message."
