Taxing Matters
As a point of clarification, the EEOC has nothing to do with Facebook's relationship with users. The EEOC only enforces the federal laws relating to illegal discrimination against employees by their employers. Federal law does prohibit places of public accommodation from discriminating against their customers based on race, color, religion, national origin, or disability. The laws the EEOC enforces covers a several additional characteristics that apply in employment but that do not apply to places of public accommodation. So while I know what you were getting at, it is not quite correct to refer to "eeoc protected classes" in this context.
And, moreover, it is still not clear to what extent websites and online services are subject to the federal law regarding places of public accommodation. This is still an emerging area of the law and one on which the courts don't agree. Ultimately it may end up having to be resolved by the U.S. Supreme Court.
