My big question here is "why"... targeting the spammers I can understand, but going after people using Facebook to have fun, which is kind of the point (it started on college campuses after all) strikes me as kind of pointless. Someone creating a profile for their cosplay persona, or pet cat, or whatever should be fine if people want to. Likewise having multiple profiles for work and personal business is just common sense. You can't really speak freely on a professional "wall" or profile, and honestly unless Facebook wants to start actually compensating people for loss of employment due to forcing these things to overlap, they should just leave it alone.
Of course I guess asking "why" is rhetorical. The bottom line is that Facebook increasingly seems to be pimping itself out as a database and selling personal information one way or another. I'd imagine the bottom line is some of their clients (legit or otherwise) were unhappy about paying for the personal information of people only to find that large portions of it were housepets or fictional characters like cosplay personas. Internet scammers probably got all miffed over wasting their breath to convince Mr. Fluffy that they are a Nigerian prince.
I can see it now.
Mr. Zuckerberg: Technically I'm not supposed to do this, but here is 10 million names of accounts that have had activity over the last three months, along with E-mail addresses, contact information, and in some cases credit card info if they happen to have purchused services through facebook. Thanks for the extra million bucks, I really needed it as the money pile next to my fireplace was getting a bit low and I need to be ready for winter.
Darth 'Sploiter: Yess, with this information I will be able to make money, if even one out of 10 thousand people bite my ads, scams, and cons I will make my money back sixfold. Assuming I can't just outright use the credit card info to drain accounts, muhwahahaha! Facebook and corperate greed are a match made in hell, and I approve.... to the 'spoiler cave.
<later in the 'Spoiler cave>
Dark Padawan Griefer: Master 'Sploiter, it appears we've received a response to our automated viagra adds, should I prepare the sugar pills?
Darth 'Sploiter: (lookin over shoulder) What is this? the response is another automated response about walking around and eating friskies... is that a picture of a cat? Our response has come from Mr. Fluffkins? How could he buy sugar pills masquerading a Viagra!
So clearly this policy is motivated by a Sith bounty on Mr. Zuckerberg's head... or probably some odd equivilent. >
