Breitbart is bleeding advertisers due to an anonymous Twitter collective

The Sleeping Giants’ approach is simple: Ask people to take a screenshot of any company’s ad on Breitbart, then tweet or email it to the company to inform them that their ads are appearing on Breitbart via their ad network.

The Sleeping Giants spokesperson said the process of contacting advertisers seemed to suggest itself:

It just seemed really simple to send a screenshot to a company showing the ads next to these incendiary articles to show them what that association looked like. Most of them, especially early on, were very surprised to see themselves there. It was a really simple thing and very easy to do.
