“At Twitter, a one-in-a-million chance happens 500 times a day.”

“The vast majority of activity on Twitter puts no one in harm’s way; my job is to root out activity that might. 99.999% of tweets pose no risk to anyone. After you take out that 99.999%, the tiny percentage remaining works out to roughly 150,000 per month. The sheer scale of what we’re dealing with makes things difficult.”

“It’s crucial that I not only predict, but also design protections for the unexpected. Twitter strips all geo-data from photos uploaded to the system.”
