Honey Boo Boo -- Girl Scouts SHUT DOWN Online Cookie Campaign

Honey Boo Boo hawking Girl Scout cookies to her hundreds of thousands of fans online is UNFAIR ... so says a rep for the Girl Scouts of the USA, so the organization shut down her campaign.

HBB posted the ad on her Facebook page -- which has 701,000 likes. She also got in the girl scouts' faces by posting pictures of stacks of boxes that she sold. FYI ... she's not selling the cookies for herself ... she's doing it for a friend.

It didn't go down well with the organization. A rep for GSUSA in Georgia tells TMZ ... they contacted her site's administrator and explained online selling is off-limits, because it defeats the whole purpose of selling the cookies -- to teach girls all sorts of things, including goal setting, people skills, etc.

So HBB's people took down the ads, but get this ... the sales she's already made will be counted.
