SAN NARCISO, Calif. (Bennington Vale Evening Transcript) -- LinkedIn, the prominent social network aimed at working professionals, updated its user agreement Monday and added a provision banning subscribers from soliciting or offering services deemed prostitution. Under a section entitled "Don't undertake the following," LinkedIn admonished its members not to "upload, post, email, InMail, transmit or otherwise make available or initiate any content that: Even if it is legal where you are located, create profiles or provide content that promotes escort services or prostitution." In what company representatives called an unrelated coincidence, nearly all male members of Congress dropped their LinkedIn accounts, stating they no longer found value in the service. Agents from the U.S. Secret Service also reportedly canceled their subscriptions on Monday, citing similar reasons.
