A second lawsuit filed in a California court this week accuses Zillow of being an "frat house" which promotes sexual and ageist harassment. This time, a single mother is suing after being fired by Zillow because she checked into a hospital to treat injuries sustained in a car accident.

Zillow has built up a $4.5 billion valuation by amassing an immense real estate database. But a lawsuit filed in a California court accuses the company of cultivating an "adult frat house" culture in which female employees are constantly solicited for sex by co-workers, ranked on their breast size, and fired if they refuse to play along.

Yik Yak may not be a household name like Snapchat, but it's almost as popular. The anonymous college bulletin board app was founded by three frat brothers at Furman University last fall and has already pulled in around $85 million in venture capital. Like other apps born out of frats, two of the founders allegedly screwed the third out of the company—only this time it was under parental supervision.

Google has become the latest tech company hit with a lawsuit for exploiting contract workers. Reuters reports that a class action suit has been filed against Google, alleging the company misclassified employees as independent contractors. The plaintiff behind the suit also alleges he was refused the overtime wages and was not paid for all the time spent working.

The legal battle between Lyft and its former COO is shaping up to be a long, ugly fight. The on-demand car company has accused Travis VanderZanden of stealing tens of thousands of secret company documents before he joined Lyft's main competitor, Uber. Now VanderZanden has fired back in a new court filing, saying he was plotting with Lyft's board of directors to dispose of the company's CEO before leaving the startup.

San Francisco got little right with their Airbnb-legalizing legislation. The home-renting startup has been accused of illegally lobbying to get the bill passed. Airbnb also helped regulators write portions of the law. Now HomeAway, the Airbnb competitor that runs VRBO, is suing to get the law overturned because it was designed with only one company in mind.

LinkedIn's business practices have been the subject of lawsuits before. This time, LinkedIn is accused of allowing paid subscribers to "anonymously dig into the employment history" of its members, violating federal consumer protection laws.

As a small business owner, a very easy way to lose the trust of others is to not give them the things you promised when they handed you money. Another way is to take that money and waste it on craziness. These men did both, ArsTechnica reports.

Uber has a long-standing obsession with skirting regulations. Now the on-demand car service is accused of breaking anti-discrimination laws meant to protect the disabled.

Silicon Valley tried to settle away a $9 billion wage-fixing lawsuit, which alleges that companies including Apple and Google colluded to suppress employee wages. But a federal judge nixed the paltry $324.5 million pay out, saying it was not enough. Now the companies behind the conspiracy are appealing, insisting the lowball figure is adequate.

Apple is now facing a class action lawsuit for unpaid wages. The suit was originally filed on behalf of Genius Bar employees in 2009, alleging Apple denied workers their legally-required meal and rest breaks. Following years of litigation in California's Superior Court, the case was certified as a class action suit today.

Silicon Valley fetishizes youth—the 20-something, white, over-worked male who will write code until his wrists tingle. That's just great, unless you happen to not be those things. Case in point: a new lawsuit against Twitter complains the company fired a 57-year-old employee because of illegal age and medical bias.

After a protracted legal battle, Reuters reports Apple, Google, Intel, and Adobe will settle a lawsuit claiming they conspired to pay their employees far less than they deserved. These companies got a very good deal.

Israeli business paper Globes reports that Waze, the navigation app Google purchased for $1 billion last year, infringes upon an open source mapping project he was part of:

Traffic accidents can happen anywhere, to any company. But a California attorney contends that a recent Uber fatality isn't like other accidents—the app itself makes drivers a danger on the road.

The volume of pure resentment spewing out of Snapchat is approaching early-Winklevoss levels: TechCrunch reports the co-creators, embroiled in legal grappling, are now asking for a restraining order against their former friend after alleged leaks to the press.

As we mentioned earlier this week, Kanye and Kim are suing YouTube creator Chad Hurley for the allegedly unauthorized upload of their lavish, geek-studded proposal ceremony. Now we've got the full legal documents, and they go out of their way to call Hurley a loser.

In the future, you'll be able to call a limousine, whenever you want one! That will be fun—but perhaps not so fun is the quiet abolition of tipping that some smartphone chauffeurs claim Lyft and Uber are pushing. Now the dispute is heading to court.

There are some forces so powerful, not even the wrought iron bonds of frat friendship can withstand them. Money is one—and so the fun-loving young dudes who made Snapchat are at each other's throats in court. Here's where it started to go bad.

Zynga, the failing company behind games you used to play like Draw Something and Words With Friends, is getting desperate as it falters: Bloomberg reports the firm is taking silly sex app Bang With Friends to court for trademark infringement.
