Facebook has disabled some advertisements about the potential side effects of HIV prevention medication Truvada following complaints that they were misleading and a “harm to public health.” The decision comes less than a month after almost 70 LGBTQ advocacy organizations signed an open letter demanding the social media giant “immediately remove” the “inaccurate advertisements,” which they claimed were targeting gay Facebook and Instagram users. “After a review, our independent fact-checking partners have determined some of the ads in question mislead people about the effects of Truvada,” Facebook spokeswoman Devon Kearns wrote in an email to NBC News. “As a result, we have rejected these ads and they can no longer run on Facebook.”
