Jeff you are right about Crossfit. They did voluntarily leave FB. "Recently, Facebook deleted without warning or explanation the Banting7DayMealPlan user group. The group has 1.65 million users who post testimonials and other information regarding the efficacy of a low-carbohydrate, high-fat diet. While the site has subsequently been reinstated (also without warning or explanation), Facebook’s action should give any serious person reason to pause, especially those of us engaged in activities contrary to prevailing opinion."
