"At first glance, this sounds like a joke, doesn't it? Sex writer Violet Blue has launched a new URL shortening service, Vbly (found at Vb.ly), called "the Internet's first and only sex-positive URL shortener."
This means that Vbly has a different policy than other shorteners. Blue, and Vbly creator Ben Metcalfe, encourage the use of this service for creating links to adult sites and other "NSFW" links. They do not run their links through filters, as the market-leading Bitly (found at Bit.ly) does. Although, as Blue says. "I think we'd remove links if we were asked to by a court or if we were made aware of anything involving illegal activity."
