The only winning move is not to play.

But even by quoting that, I'm still playing (albeit by attempting to jump out into the meta game).

So the only ones who are actually not playing are the ones who are clicking away from this vapid comment page and moving on with their lives.

You're right. Every form of communication indicates signalling, you're literally sending signals from one entity to another. The only way to stop signalling is to stop communication between entities.

Deleting facebook is a signal. Abandoning social life altogether is a signal too.

I believe the only way to stop is to generate white noise - by sending signals so mixed that those who observe stop trusting them

I'm sorta reminded of the Onion article from years ago, "Area Man Constantly Mentioning He Doesn't Own a Television":

Area man doesn't signal.
