Despite the fact the article makes it clear this problem is way to detect, it doesn’t matter. Facebook created the problem, they don’t get to just say, “it’s too hard” and throw their hands up. If they can’t fix it then they should scale back their operations until it’s a manageable size.

Imagine I’m out in a park firing guns into the air and you come up to me and say, “don’t you know those bullets might come down somewhere and hurt someone?” And I say, “do you know how hard it would be for me to calculate exactly where each bullet would land and where I can aim it safely?” Would you just walk away and say, “oh yeah, that’s too hard of a problem to solve, carry on”?
