Profiling people for advertising, building shadow profiles, buying 3rd party user data, tracking people across the web, devices and geographically, psychologica

  Ok, I'm going to assume that you're somewhat technical given where we are. First off, if I estimate a series of numbers on you and those result in you being served a set of ads, is that wrong? If so, can you help me understand what's wrong with that? Shadow profiles are mostly bullshit, yes data was collected for non users due to how the SDK and pixel worked. This data was all assigned to one user ID and was filtered out by basically everyone using that data. I'm a little confused as to why buying third party data is wrong, the problem with this is that it's legal to collect and sell the data. Speaking as a psychologist can you clarify what's wrong with psychological experiments? I think your point about optimising for engagement was definitely a mistake, given the downstream consequences. However, they needed to find some way of ranking feed after Zynga almost killed them (a chronological feed would have been all Farmville all the time for a number of years) and they picked likes. They also optimized for time spent but people complained about that so they started optimising for comments and shares which made everything worse, sadly. Limiting post reach for pages was a legitimate business decision, particularly given the ranking constraints. Got any more problems with them?
