According to reports, Twitter's last-week-launched Vine video-sharing app has apparently been hit by the porn issue; having already become a popular venue for sharing sexually explicit content.

While the Thursday-released Vine video capture service from Twitter was essentially launched with the aim of giving the users to embed six-second video clips in their messages on the popular microblogging site, reports have revealed that pornographic video clips have started showing up on the new app.

With a number of Twitter users seemingly using Vine to tape male genitalia and porn films off laptops and TVs and laptops, The New York Times' Nick Bilton - pointing out that Vine had developed a porn problem - has drawn attention to the fact that searches for #porn, #sex, and other linked tags unfold quite a few videos that feature male exhibitionism and other sexually explicit video content.

The porn issue that has reportedly cropped up in Twitter's new Vine service is probably a result of Vine's terms of service which do not specifically prohibit the sharing of sexually explicit content via the service.

However, since Twitter does encourage its users to use good judgment while posting content on the site, a Twitter representative told CNET that `offensive' videos can be flagged by the users, and added: "Uploaded videos that are reported and determined to violate our guidelines will be removed from the site, and the user that posted the video may be terminated."
