The messages in my IRC channel don’t appear based on how incendiary they are. They are a strictly chronological timeline with no “viral amplification”. Closest we had to that was people reshaping bash.org links.

I mean, I definitely recall the need to turn off unauthenticated DMs because of all the IRC bots recruiting racists to their "ChimpOut" network, which purported to ban black people. So it's not like you really need viral amplification to coordinate a rally, nor is it that hard to fake.
