The new additions to the rules, as seen below, are far more encompassing and direct a move than the previous surreptitious banning of hashtags ever was.
“Pornography and Sexually Explicit Content: You may not post content that is pornographic or sexually explicit—even if it is of yourself or marked as sensitive. For more information on this policy and its application, please see this help center article.”
In a blog post from Vine itself the company describes the pornographic content that was being shared as a “very small percentage of videos that are not a good fit for our community” and that while the Vine team “don’t have a problem with explicit sexual content on the Internet –– we (they) just prefer not to be the source of it.”
The blog post was met with some anger from users in their subsequent sharing of the blog post with comments like ” i guess giving people the option of marking a video NSFW wasn’t enough. vine has banned all “explicit” videos from the service” being one of the softer worded responses to be found.
Vine had been used by many in the adult industry as an advertising platform to build their personal brands through social media after Instagram, which many perceive to be the main competitor to Vine, instituted a massive crack down on explicit content related hashtags.
