Zuckerberg denies knowledge of Facebook shadow profiles
Facebook OpenGraph v2 stopped the ability of api app developers from getting friend data without their consent.<p>For the most part &#x27;shadow profiles&#x27; are dead as of 2013-ish when OpenGraph v2 came out. Lots of scammy Facebook companies died because of this, if you remember many game companies also suffered a bit like Zynga and threatened to leave, they were given special access to still do it for a while and I assume others like CA possibly.<p>With v2 they also shut off using global Facebook user ids and moved them to a per app basis so you can&#x27;t correlate outside your app, you&#x27;d have to correlate with other identifiers like email or deeper data comparing.<p>Facebook also turned friend access into invitation lists where the other user had to agree and join the app themselves before you could pull their data.<p>Facebook knew about shadow profiles and they already addressed it.
