I feel like everyone knows that there are always dark alleys regardless of how bright the streets are. The Internet has always had dark alleys the size of California freeways. The most recent incarnations of these are 4chan and 8chan. The forums most pertinent for the GamerGate conversation on 4chan (boards.4chan.org/v/) and on 8chan (8chan.co/gg/). They are absolutely Not Safe For Work! They are barely safe for people who actually like other humans to tread through. The addresses for the dark alleys will change, as they have through time. The users always feel like wherever their current home exists sells out, which precipitates a move to a new, more welcoming space for what has always existed online.
