Already catching flak for a hack of millions of accounts and for secretly scanning emails for U.S. intelligence, Yahoo is facing yet more criticism--this time from a former employee.

Silicon Valley Business Journal editor-in-chief Scott Ard has filed a lawsuit in federal district court in San Jose, California, against Yahoo alleging gender-based discrimination against men, according to The Mercury News. Ard reportedly worked at Yahoo for three and a half years, and served as the company's editorial director, per his LinkedIn profile.

According to the News, the lawsuit claims CEO Marissa Mayer "encouraged and fostered the use of (an employee performance-rating system) to accommodate management's subjective biases and personal opinions, to the detriment of Yahoo's male employees."

A Yahoo spokesperson declined to comment directly on the lawsuit to the News but defended its employee evaluations:

"Our performance-review process was developed to allow employees at all levels of the company to receive meaningful, regular and actionable feedback from others ... We believe this process allows our team to develop and do their best work. Our performance-review process also allows for high performers to engage in increasingly larger opportunities at our company, as well as for low performers to be transitioned out."

Ard's lawsuit is not the first of its kind, points out Gizmodo:

"This is the second time Yahoo has gotten sued for allegedly stacking the deck against men. In the first lawsuit--also filed in San Jose federal court in February of this year--Gregory Anderson, who ran Yahoo's cars, small business, shopping, and home sections, alleges that 'female employees were more often allowed to leave voluntarily and were given time to find new employment, while males were more often fired.'"

Seems like Yahoo won't be catching a break any time soon. The New York Post reported this week that Verizon is seeking a discount of $1 billion on its planned purchase of Yahoo, from an original price tag of $4.8 billion. Yahoo was once valued at $125 billion.
