Flash Mobs are kind of a limit case of the first amendment’s right to peaceable assemble. I have no idea if they have similar constitutional protections in India. I seem to recall that Gandi was a fan of mass nonviolent resistance because it was a practical solution to pent up disaffection, better than violence.

Meanwhile I highly recomend the short story Larry Nevin on Flash Crowds, it’s in the book “Flight of the Horse.” His solution to this class of denial of service attacks was laws – to date I’ve don’t think I’ve seen another solution that works.
