"I've directed our teams to invest so much in security on top of the other investments we're making that it will significantly impact our profitability going forward", Zuckerberg said, "and I wanted our investors to hear that directly from me".
"Protecting our community is more important than maximizing our profits", Zuckerberg said in a statement.
