I can say for a fact that many didnt use internet commynication. What you are seeing here are many leaders of small affinity groups on the periphery, all the way up to higher level organizers. Many useful idiots who got word through flyers or word of mouth are not represented here, although this list is rife with many low level suckers who obviously did. With any luck this will lead to prosecutions, but knowing Portland it'll just read like a linkedin of revolutionary larpers to harvest for jobs with the city.
