There is an old MGTOW/RedPill saying… 
“We don’t advertise, we just watch them arrive”. 
MGTOW advertises itself in the same way that Nostr or even Bitcoin does. How long can people suffer the debasement of their currency? The silencing of their opinions? The very nature of advocating for something that resonates this deeply with the human experience advertises itself. People will go looking. Just be ready when they arrive.
