The only way there could would be if we enter some Make Believe Scenario where people sign up and pay for access with specific stipulation of freedom of speech and all of that and then the company refuses it. Even then, the most damage one could argue for is a refund of the unused portion of that fee. I am unaware of any place that stupid. The standard TOS of any place basically affirms that, yes, you are a guest in a privately owned place that the owner can capriciously do whatever he wants with it.
I understand you do not argue otherwise, but it appears some think they can remake reality through statement. Same way I insist that I can park in that handicapped spot because the PATRIOTS WON THE SUPER BOWL!!!1!!!
The police and towing companies are, of course, haters. Probably Faider fans. Definitely anti-Freedom.
THERE--JREF--was a great example of a forum that promised free thought and all of that and utterly failed to deliver it. It became "whatever D'Rat wikes and agrees with" along with various Kool Kidz who licked his hindquarters. Some, like UpChuck, lied about what they did.
And the legal recourse is what?
There are others that are worse. All one can do is recognize that such is not what it claims to be, pretends to be, mark it as hypocritical, then move on to watch Your Mom's Webcam.
But then, I do not know, maybe someone can indict Facebook in a Common Constitutional Law Court under RICO. . . .
