“But just as a meatpacking company that sold tainted beef, over and over again, that made people ill, would eventually see a decline in sales, so too a social web which is infected with the abuse will inevitably see a decline in usage. I can put that in economist-ese if you like: network effects power social technologies, but abuse is a kind of anti-network effect, not a positive one, but a negative one: I don’t benefit from you being on the network, I suffer.”
