If you want to be truly against establishment, here is what you can do with social networks: do not use hashtags. If it is not too much trouble, share the content, not the links. Dole out your opinions and wisdom in the littlest of ways, do not write a blog post just to say how good your lunch was or how awful the traffic is. Humanise. Simplify. Do not go after your followers; remember who is following. Confuse the network analysts.
Because anarchists do not form groups.
