A would-be challenger to Google Inc. said Tuesday it is suing the Internet search leader for alleged abuses that include illegally rigging its prices to thwart potential competitive threats.

In a 38-page page complaint, TradeComet.com LLC accused Google (nasdaq: GOOG - news - people ) of manipulating its system for setting ad rates to make it too expensive for a specialty search engine called SourceTool to promote itself within Google's vast online marketing network.

In a press release, TradeComet said it filed its antitrust lawsuit in a New York federal court.

Google said it hadn't reviewed the allegations as of late Tuesday, but the Mountain View-based company reiterated its belief that there are plenty of other online advertising options, including networks run by rivals Yahoo Inc. (nasdaq: YHOO - news - people ) and Microsoft Corp. (nasdaq: MSFT - news - people )

"As we have consistently made clear, the advertising market in which Google operates is highly competitive, and advertisers have a huge range of choices," Google said in a statement.

TradeComet's lawsuit is the latest legal action to allege Google has used its widening market power to create a monopoly that enables it to bully rivals or squeeze out Web sites that it doesn't like.

Google processes nearly two-thirds of the Internet search requests in the United States and sells an even larger chunk of the text-based ad links that appear alongside search results and other content on millions of Web pages served up each day.

One of Yahoo Inc.'s largest shareholders, Ivory Investment Management LP, is urging the Internet company to pursue a sale of its search unit to Microsoft.

In a letter to the company's board, the investment firm proposed a deal Wednesday in which Microsoft (nasdaq: MSFT - news - people ) would acquire Yahoo (nasdaq: YHOO - news - people )'s search engine and Yahoo would retain 80 percent of revenue generated by search queries on its own site.

Ivory said Yahoo could get about $15 billion from Microsoft for the search platform alone, a deal it said would give shareholders a value of $24 to $29 per share, or more than double Yahoo stock's closing share price Tuesday of $12.19.

Yahoo shares rose 62 cents, 5.1 percent, to $12.81 in morning trading Wednesday.

Yahoo Chief Executive Jerry Yang said recently that he would resign, a response to shareholder discontent that brewed after Yahoo rebuffed a $47.5 billion takeover offer from Microsoft for the entire company. Before stepping down, Yang said he was still open to some kind of a deal with Microsoft, after antitrust concerns sank Yahoo's planned advertising partnership with Google Inc. (nasdaq: GOOG - news - people )

Microsoft CEO Steve Ballmer has said a takeover of Yahoo is off the table but has expressed interest in the company's search business.

In the letter Wednesday, Ivory took Yahoo's board to task for not seeking a deal with Microsoft more aggressively and accused the company of ignoring shareholder interests. The firm holds 21.4 million, or about 1.5 percent, of Yahoo's shares.

Newly minted doctors--some beaming, some brooding--stared up at me from their yearbook's glossy pages.

Self-conscious, I scanned photo collages for any recognizable feature. Like those deep creases that form when I smile and my cheeks puff out too far over my mouth. Or perhaps a short stature ran in that side of the family. (I'm very nearly 5'4".) Scrutinizing the male fourth-years for hair lighter and straighter than my mom's, I felt uneasy.

I wasn't looking for a dad. I was looking for a donor.

In 1984, my mom wanted to have a baby. She was unmarried and 38 at the time, with a Ph.D. in educational psychology, but adoption agencies denied her an infant because her household would have only one income. Artificial insemination became her only recourse. She was, as they say, a single mother by choice.

She was also a pioneer. In 2005, the most recent year for which data is available, 52,041 infants were born as a result of assisted reproductive technologies, according to the Centers For Disease Control and Prevention (CDC). Experts estimate the fertility industry is now worth $3.3 billion.

There aren't comparable figures for 1984, but it's telling that the CDC only started tracking these procedures in 1995. Today, women can peruse baby pictures, SAT scores and page-long descriptions of potential donors. Two decades ago, none of this elaborate scaffolding existed.

My search--which my mom blessed because, heck, she was curious, too--started off on a promising note. The two doctors my mom saw are both still practicing. I called one twice and even stood in his office lobby so I could catch him between patients. He looked at me kindly and said, vaguely, that he remembered my mom and would call me back. He never did.

Vigilantes are roaming Chinese cyberspace, laying the identities of perceived wrong-doers bare.

For Wang Fei, the journey from high-flying advertising executive to jobless national hate figure began with an extramarital affair. His disgrace was absolute and immediate. Rarely is there any other outcome after one becomes a target of the "human flesh search engine."

This is the name given to the Internet-powered manhunts that have achieved notoriety across China this year. A human flesh search engine is where thousands of volunteer cybervigilantes unite to expose the personal details of perceived evildoers and publish them on the Web.

The consequences for those on the receiving end often transcend the virtual world and can include loss of employment, public shaming, even imprisonment. Conversely, the most voracious "flesh hunters" are widely seen as the online equivalent of lynch mobs. Many of the participants are too young to draw a loose comparison with the "public criticisms" and purges of the Cultural Revolution more than 40 years ago.

In Wang's case, his wife posted a series of blog posts expressing her devastation over her husband's infidelity and then leapt to her death from their 24th-floor apartment. Almost instantly, an online mob--the human flesh search engine--enraged at Wang's philandering, exploded into life.

Within days, photographs of Wang appeared on numerous Internet forums alongside his phone numbers, address and national ID number. Slogans were painted on his front door. One read: "A blood debt must be repaid with blood."

His lawyer said Wang was forced to resign from advertising agency Saatchi & Saatchi after its Beijing office became subject to abuse and that he was harassed by strangers in the street.

Wang is by no means alone. The human flesh search engine first shot to prominence in 2006, thanks to the macabre actions of Wang Jue, a nurse from Heilongjiang Province.
