National Science Foundation: Porn Hotbed?

Iowa senator Chuck Grassley sent a letter to the leaders of the National Science Foundation after the agency allegedly did not pursue punishing employees caught accessing pornography on their work computers.

Grassley sent the letter after an unidentified whistle-blower informed the senator of the NSF's inaction, Politico reports. Despite the agency's blocking of pornography websites since the original incident revealed in-office porn viewing use in 2009, employees still shared photos through Microsoft PowerPoint.

An NSF official told Politico there have been "zero incidents" since online filters were added.

One worker was pegged as wasting as much as 20% of his work time viewing pornography, equaling an estimated $58,000 in lost salary. That employee has since resigned.
