Just a week after Facebook went public, its chief operating officer made headlines for a possible click fraud gaffe.

Sheryl Sandberg addressed the graduating class at her alma mater, Harvard University, ending with a joke that caught the attention of several financial reporters.

“We’re public now, so could you please click on an ad or two while you’re there?” she said.

Publications like Reuters and Forbes picked up on the slipup, with writer Tim Worstall saying, "Just to be clear here: I do not think she was encouraging click fraud, it was a joke. But it’s the sort of joke that a senior executive of a public company probably shouldn’t really be making."
