A made-up character representing Tribe management, "TOU Guy" began aggressively patrolling the site in December, removing nude photos and sending reprimands to authors of offensive material. His enigmatic silhouette popped up in e-mails threatening to banish people who violated the rules.
TOU Guy made Tribe safe for advertisers who had flocked to the site as it became more popular. But original members felt betrayed, and 1,400 of them rebelled and left to build a new site (Free-Association.net) where they can once again discuss anything from magic to transgender issues without restriction.
Social networking Web sites such as Tribe, Friendster, MySpace and Facebook grew by 50 percent last year, according to Nielsen-NetRatings, making them some of the most popular destinations on the Internet. But the rapid success is testing the limits of how the Internet's freewheeling free speech can coexist with its power as a medium for advertising and commerce.
Pleasing squeamish advertisers
Although many sites started out as grass-roots places where friends could meet and connect for free online, nearly all have been purchased over the past several years by big media companies looking for ways to profit from the millions of members by selling advertisements. Many advertisers are squeamish about the nudity, vulgarity and sex that gather on sites where users can post anything that interests them.
"What advertisers are excited about with this new medium is, it's a good way to reach young people and people who are buying their stuff," said Lucian James, president of brand marketing firm Agenda Inc. "By restricting it too much, the danger is they turn it into something like old media. People will flee away from something that looks like an old police model or one that looks like it's being run by parents."
The rules about what a member can post to some of these sites vary greatly, and many sites are experimenting with new methods of enforcement. Some, such as online video site YouTube.com, employ a community-policing approach that relies on members to report offensive material, which the company reviews for removal. Others, such as online video site vMix.com, take a more active approach, hiring people to view every photo and word before it is posted.
MySpace.com, the most popular networking site with 75 million users, said it has recently stepped up its efforts to ensure that the content posted by members follows no-nudity and no-pornography rules. The company uses a filtering software that tries to recognize nudity in photos before they are uploaded, and it also employs people to screen some photos and videos and address safety concerns.
Child safety bill
Last month, Republican lawmakers filed a bill, backed by House Speaker J. Dennis Hastert (Ill.), that would force schools and public libraries to prevent children from accessing any social networking site where minors could be exposed to "obscene and indecent material." Rep. Michael G. Fitzpatrick (R-Pa.), one of the bill's sponsors, said it is an effort by lawmakers who call themselves the "Suburban Caucus" to address the concerns of parents who are alarmed by the high-profile arrests of child predators who use the sites to contact teens.
The bill has not been scheduled for a hearing, and it is unlikely to move ahead, given Congress's busy schedule before the end of the session. Some legal experts think the bill would not be constitutional anyway, because it would inherently limit children's access to the Internet and infringe upon their freedom of speech.
"Kids are being kids on social networks -- they're doing exactly the same stuff we did when we were kids. The difference is because they're doing it on this public space, we have a window into their activities," said Lauren Gelman, who has studied lawsuits related to MySpace as associate director of Stanford University Law School's Center for Internet and Society. Social networking sites "have to get this right in a way that they don't alienate their users but they also have to get it right for their investors and advertisers, so you don't end up with a Honda ad next to a pornographic picture," she said. "They have to balance both of these interests."
As the Tribe example shows, the bonds that form among online friends can be incredibly strong and easily mobile, making the task of monitoring or regulating them increasingly difficult and complicated.
Founded by enthusiasts of the annual Burning Man counter-culture festival in Nevada, Tribe initially relied on users to place a "mature" label on any adults-only photos or content on their personal profiles. The site requires users to be at least 18 years old to join, but the policy is difficult to enforce and visitors can still view all of the content.
The community-policing rules changed in December, after a broad, pornography-related decision by the Justice Department left the company worried that it could be held liable for sexually explicit material posted by users and after advertisers expressed concern. "Our advertisers and our investors aren't particularly happy with the adult content there," said Darian Patchin, spokesman for Tribe Networks Inc., which runs the Web site. "We needed to do something that enables us to be a successful business and that our investors are okay with."
Policing sparks outrage
Tribe, a San Francisco firm that received initial funding from The Washington Post Co. and Knight Ridder Digital, announced that as of Dec. 20, 2005, it would remove all "mature" content from the site. Such discussion groups could continue to exist, but to only members who signed up for them. They would become invisible to everyone else.
That move, coupled with the "TOU Guy," sparked outrage. Some members tried to test the limits. Matthew Puffer, who uses the screen name "Mateo," started posting adult photos, just to see if Tribe would kick him off. (Tribe eventually blocked his server from accessing the site.) He posted lewd photos of "soft" pornography but also some of artwork that involved nudity. Puffer said the TOU Guy ignored some photos, but removed images of ancient Peruvian pottery featuring naked figures. "The way they implemented their TOU was so completely arbitrary, it was ridiculous," Puffer said.
"They had this whole period of being overbroad in what they were censoring," said Deborah Pierce, a former member of Tribe who left to start Free-Association. "A lot of Burning Man photos of naked people were being taken down. They weren't sexual. They were just of naked people at Burning Man."
The move told many members that Tribe had become something far different from its origins.
"It doesn't surprise me that we have really strong feelings" by members about the changes, Patchin said. As one of the company's earliest employees, he agreed that the company had changed a lot over time and that it had refocused its efforts to become a cross between MySpace.com and Craigslist.org, a Web site for free classified advertisements. But Patchin said Tribe is a business and ultimately has to be responsible to its funders.
As for the loss of some of its members, Patchin said the secession hasn't made a huge dent. Tribe recently had to lay off about half of its 25 employees as it put costs more in line with revenue from online advertising. It has more than 500,000 members, he said, and is still growing.
