The tactics were probably forged in the underground while it was not wise to speak openly about it, always with the law or society breathing down their necks, so I am not surprised the tactics aren't the cleanest or most innocent. Once this gets enough traction, it might get plenty of followers. If my kid would come home with half green, half pink hair, we would have to sit down and find the origin for that, I would not be very amused. But same applies if my kids would bully other kids for any reason.
