In the past week, the charity Invisible Children and their viral “Kony 2012” campaign has skyrocketed in visibility- and along with it, criticism of the org and its motivations has been raised. (Amusingly, late-night talk show host Bill Maher said that upon the appearance of the Kony 2012 campaign, he’d surged several points ahead of Mitt Romney in polling.)

If Invisible Children’s campaign to raise awareness did anything, it was catapult its lengthy video to the forefront of the slacktivism foray on Facebook and Twitter. For a solid few days, the number of Kony 2012 posts were staggering, but soon people started wondering who was behind the campaign, and some troubling allegations about Invisible Children and the Kony 2012 campaign emerged.

Invisible Children has been dealt another blow in the charity vetting realm, with the Better Business Bureau weighing in in a blog post today. Some of the allegations slung on social media about the charity included assertions that only a small portion of the charity’s funds went to charitable works, and in their post, the BBB begins:

“The BBB Wise Giving Alliance has tried for six years to get Invisible Children to cooperate in a charity review. Since 2006, BBB has sent 18 letters (12 via Certified Mail) to the non-profit behind the Internet phenomenon Kony 2012 video, but has received no response.”

The business vetting organization says that while the charity is good at shining a light on atrocities, they seem to be reluctant to submit their organization to any similar scrutiny:

“I don’t understand their reluctance to provide basic information,” says H. Art Taylor, President and CEO of the BBB Wise Giving Alliance. “The whole point of the effort is to shine the light of truth on a terrible atrocity, and yet they seem to be reluctant to turn that light on themselves. It’s really unfortunate, because their campaign has the potential to inspire and galvanize millions of young activists and future philanthropists.”

The post continues:

“We don’t assume that nondisclosure is proof of bad faith,” continued Taylor, “but the vast majority of national charities we contact (70%) demonstrate their commitment to transparency by providing the Alliance with requested information so that we can produce reports for public inquirers.” The 20 BBB Standards for Charity Accountability offer the most rigorous evaluation of nonprofit organizations available.
