Wash. Post – Drug dealers are turning to Facebook and other popular social media sites to peddle steroids, which are illegal without a prescription, raising more questions about whether the companies are properly policing their platforms. Those substances are being aggressively sold or marketed through posts and videos on sites including Facebook, Instagram, YouTube and Twitter, according to new researchby Internet safety nonprofit group Digital Citizens Alliance and cyberintelligence firm GiPEC. During the first half of the year, the researchers say they found more than 100 examples of such pages or posts.
