> Also their bulk contact upload. Take any data leak of email addresses, bulk upload them as contacts and then correlate email addresses to social profiles. This is one of those functionality aspects all these social/networking sites fall foul of one way or another, be email or phone number relational suggestions. That and the aspect of this scraping of phone numbers or emails - even with the users permission, kinda moots the owner of those email and phone details. But does seem that once you give anybody your email or phone number, it kinda one way or another falls into the public domain level of privacy. Heck how many contact details via email or phone numbers do these sites hold on people who never even held an account with them. Be nice if the law and data privacy had some global standards as this region/country by country aspect does nobody any good and in a World in which taxation works with the same model, do we really want to let data protection end up with data havens in much the same way as tax does.
