Name address and so on i, well, understand if you buy something online to fill that in. But sns and id??? Thats all kinds of stupid. Why would you give thata willingly to fb? Its not a government entity or even a bank.
Not quite, but pretty close. You still hold copyrights in anything protected by copyright for example. They just have a perpetual license to use your work. We really ought to be working on laws to protect privacy and limit corp content piracy without explicitly clear opt-ins.
Back in the paper spam days, some folk would stuff the "postage paid" envelopes with junk and mail them back to troll the companies. Setting up a junk address with an autoresponder would be pleasing, but probably would get tagged illegal.
