There are policies Facebook has issued, but there is always room for interpretation - and in light of current changes, the interpretation is a lot more stringent now in contrast to before.

Facebook's probably getting strict because its preparing for a relaunch of its design in July. Or — and this pure speculation — the third-party security firm Rock You's rival Slide hired to audit its own privacy might have gotten paid a little extra to take a close look at the competition and alert Facebook to any infractions. We wouldn't put it past hypercompetitive Slide founder Max Levchin and his crafty sidekick, Keith Rabois.

Despite the blow from Facebook, Shen told SAI that unlike its closest competitor, Max Levchin's Slide, RockYou intends to keep developing for the platform. RockYou will need to — especially if developer Blake Commagere wrestles back control of his popular Vampires and Zombies apps. (Photo by califrayray)

Why the $150 million drop from March to June? In part, RockYou founders Lance Tokuda and Jia Shen can blame Facebook's spam-killing redesign, which will eliminate some of the tools RockYou used to increase the popularity of its widgets. But our source takes a shot at Tokuda and Shen, too. He tells us:

The reason the round took so much time was because the valuation expectation was inflated. They had unrealistic expectations and "team" really matters when you raise capital.

Not that that's so unfair of a shot, considering Tokuda and Shen's lawsuit-wracked history.

• F is for Fitzpatrick, and "hookers and blow"
• L is for Levchin, who never goes slow
• P is for Parker, the Valley's bad boy

• Joe Green (top left) has raised $7.3 million for his Facebook application, Causes. Which would be more impressive had the funding not come from Peter Thiel's Founders Fund. Thiel is an investor in Facebook, and has a vested interest in creating the impression that Facebook appmakers are worth something.

• Drew Houston (not pictured) runs a company, Dropbox, which offers online file storage, a service users can't get from anyone else. Except AOL, Google, Microsoft, and Yahoo, and a good dozen other startups.

• VideoEgg CEO Matt Sanchez (top, second from left) tried to compete with YouTube and failed. Or "evolved," as BusinessWeek put it, into an ad network for Flash games, a crowded field that so far has garnered VideoEgg gross revenues of $300,000 a month. The magazine lauded Sanchez for raising $27 million in venture funding; it should have asked instead how much is left.

• RockYou cofounder Jia Shen (bottom left) launched his widget startup while working for another company, Iconix, according to IM chats produced in court. He and cofounder Lance Tokuda settled a lawsuit with iconix last year. They're now trying — so far unsuccessfully — to raise another round of venture funding, or sell the company.

In Slide, RockYou now faces a very well-financed rival which took $50 million from its new investors. And Slide has real advertisers like McDonald's, AT&T, and BP; RockYou is better known for its plan to charge other Facebook-app makers to advertise their wares. (Does that strike anyone as a pyramid scheme?) Finally, there are RockYou's cofounders themselves — perhaps the biggest reason they won't get $400 million for RockYou.

Last year, they settled with their ex-employer Iconix, which charged them with developing the idea for RockYou while still working there. The episode was messy, and public. One would think RockYou's prospective investors would take it into account before putting their money in Shen and Tokuda's hands.
