Last Thursday (Jan 24), Twitter released Vine, it's new app for iOS devices which allows users to shoot and post short six-second videos. Since its release, there have already been a few new waves.

Since then Facebook has already had to update its policies regarding third-party app developers due to the fact that they've made Facebook's friend-finder tool unavailable to Twitter Vine. Facebook's new policy stated, "You may not use Facebook Platform to promote, or to export user data to, a product or service that replicates a core Facebook product or service without our permission."

The more amusing side-effect is that already by Friday (the follow day after release), Twitter Vine has a porn problem. The app has quickly become very popular for shooting male genitalia and porn clips.

Vine's terms of service don't forbid such use, but it is very much frowned upon. The terms of service states:

You are responsible for your use of the Services, for any Content you post to the Services, and for any consequences thereof. The Content you submit, post, or display will be able to be viewed by other users of the Services and through third party services and websites. You should only provide Content that you are comfortable sharing with others under these Terms.

Users can report videos as offensive to get Twitter to display a warning at the start of the video clip, and if they are found to violate the terms of service they will be removed, and the user could be banned.

Also, even though this doesn't violate Twitter's terms of service, it could violite those of the Apple App Store. They have stated in their terms that they will reject any apps which contain pornographic material, and Apple has done so in the past with photo-sharing apps for similar reasons as these.
