Utter, utter BS! There is no way Facebook could accidentally scrape and upload contacts, to develop something that could log into a webmail account and go through the contacts and then send them to Facebook would take quite a lot of development work and simply could not happen by accident. It's like building a house without planning permission and telling the council you just bought some brick and dumped them on your land, but they just so happened to fall in such a way that they landed in the shape of a house.
Please tell me they won't get away with pretending it was an accident??
That's before you even look at them acutally asking for your password, WTF?? That creepy little android c#nt Zuckerberg needs to learn some respect.
