Consider it an unspoken, but universally true rule: if it can be used for porn, it will be. Texting, Snapchat, Skype and video streaming technology have all fallen to mankind's more base desires, and now, Vine has too. According to a post on the Vine blog, the company has determined that a small percentage of its users are posting videos that "are not a good fit" for its community. In response, Twitter has changed its terms of service to ban sexually explicit Vines, specifically prohibiting videos of sexually provocative nudity, obviously aroused genitalia, sexually graphic art or animation and clips of sex toys being used erm.. as intended.

That said, the company doesn't want you to think it prudish -- nudity in natural, artistic or documentary context (such as unclothed models in an art class or nude protesters) are A-OK, as are the swaying hips of any fully clothed erotic dancer. "We don't have a problem with explicit sexual content on the internet," the company wrote. "We just prefer not to be the source of it." Fair enough, but if we were to guess, we'd say the move has more to do with upsetting App Store policies than maintaining a squeaky clean community.
