More than a thousand individual Twitter profiles advertising everything from private escorts to dominatrix services were identified, many of which appear to violate the San Francisco-based company's terms of service. Twitter's terms dictate that the message system -- limited to 140 characters per message or tweet -- not be employed for "any unlawful purposes or in furtherance of illegal activities." Further, the company's rules prohibit pornographic images from appearing in "header photos or user background." How these rules would be enforced was not spelled out.
TheStreet discovered that at least two international networks of escorts rely on the Twitter platform to promote and execute their services.
The reach of marketing pitches made by escort services on Twitter surprised even those plying the trade.
Cassie, a woman in her 20s who works as an escort in the Midwest and said she doubles as a prostitute, said she was unprepared for the international calls she received.
"It is definitely a concern to me that my information was broadcast there," said Cassie, who asked that her real name not be used, after TheStreet notified her that the international escort service, ErosGuide, repeatedly tweeted out her profile offering services.
Notified by TheStreet of its investigation that revealed that escort services were using Twitter, Rep. Chris Smith (R., N.J.) urged that Congress investigate. Smith sits on the subcommittee investigating human trafficking, which held hearings Monday on prostitution at sporting events, including this week's Super Bowl in New Jersey.
Addressing Ambassador-at-Large Luis CdeBaca of the U.S. State Department's office to monitor and combat human trafficking, Smith asked at the subcommittee hearing that he speak to U.S. Attorney General Eric Holder to initiate a crackdown on Twitter, Backpage, Craigslist and other social media "that are the conduit for this terrible exploitation of women."
"I'll certainly relay that, sir, and I would love to hear more about the information on Twitter," CdeBaca said.
Smith's comments during the hearing followed an interview with the TheStreet in which we provided the congressman evidence of dozens of escorts and prostitutes in the New York City area listed on Twitter in advance of this year's Super Bowl in New Jersey.
Following that meeting, Smith, who serves as chair of the House Foreign Affairs Subcommittee on Africa, Global Health, Global Human Rights and International Organizations, said he plans to convene a House of Representatives subcommittee hearing later this year, and intends to ask Twitter executives to testify on Capitol Hill to address the issue.
"I'm going to look at putting together a hearing to focus on Twitter," Smith said. "We'll look to do a hearing very soon."
This isn't the first time Twitter has been brought into a national debate. Shortly before the company's November 2013 initial public offering, CEO Dick Costolo publicly defended the company against criticisms that the board of directors lacked women members.
Now, some of Costolo's detractors say the escorts who violate Twitter's terms of service, and the company's response, represent a bigger problem in Silicon Valley and the technology community.
When asked why Twitter didn't remove these accounts, similar to the one pictured above, a Twitter representative who spoke on background provided no comment other than to cite the company's policies, terms of service and guidelines for law enforcement.
"When you're a public company you're held to a higher standard than you are when you're a private company", said Vivek Wadhwa, a prominent Silicon Valley academic and regular blogger on tech, including subjects like Twitter. "They can't just sit back and say, 'not our problem'."
Facebook operates software and employs individuals to remove offensive content or material that violates the social network's terms of service. To be certain, the system has committed some serious blunders. Arguably, Facebook has acted to correct problems, which sometimes succeeded and other times have been met with criticism.
In 2013, LinkedIn changed its terms of service so that users could not "create profiles or provide content that promotes escort services." The company last year also reduced the minimum age of participation to 13-years-old.
While Twitter doesn't force escorts off its network, beer brands, for instance, require Twitter users to go through a multi-step process before becoming an approved follower of a brewer.
To follow Budweiser's main account, a user must go to the @Budweiser Twitter page and click follow. But that's just the first step. The Budweiser account then sends the user a direct message that states:
"We know it's a pain, but you can't follow @Budweiser unless you go to age.twitter.com/verify/age/?so... within 24 hours to confirm you're 21+. Thanks!"
An external company, Salesforce Buddy Media, administers this verification process, but it's not mandatory.
"It's called 'age screening,' and it's a complimentary feature offered to brands to prevent these underage Twitter users from following accounts with what we call 'age restricted content'," a representative for Salesforce Buddy Media confirmed. "The alcohol brands actually requested it; they requested it, [saying], 'Hey, can you guys put something together?' to protect them."
