There are a few antifa orgs with online presence, such as the one linked above and Torch Network, that keep tabs on this group and post thorough dox identifying many of its members. (its membership remains stagnant around 200-250 according to its leader in leaked internal communications)

Most of their activities are limited to propagandic stunts to try and gain attention: flash mob demonstrations, attempting to march alongside irrelevant right-wing protests, petty vandalism of memorials and putting up stickers. Like culture jamming minus the whole culture part.

This article shows a right-watch group in action, quickly removing propaganda before sunrise and preventing the advertisement of this propaganda organization.
