Clearly I need to step it up. I was (unsurprisingly) surprised at what I've observed they've managed to correlate. I run standard pi-hole, resist fingerprinting, and normally go through a VPN (mainly because I'm on public wifi half the time when travelling). I haven't logged into facebook in about four years, just did it for the first time today to see what's been correlated.<p>Aside the mountain of irrelevant notifications, here's what I've observed in this report that's concerning.<p>1. Albeit some data has been correlated properly (banking applications which is scary on it's own part it's sending data to facebook, imgur, Xbox, my telco provider, and a few misc blogs I've visited a handful of times per year), it's correlated a significant amount of data that may not belong to me (good thing, I suppose?)<p>2. Why the heck are banking applications sending data to Facebook as "CUSTOM", with no context? For example, RBC bank in Canada sends "CUSTOM" data (haven't been with them for over two years, but all interacts labelled CUSTOM) and Facebook will not give any more context on the <i>exact</i> data it received. Little scummy, Facebook.<p>Well, time to sweep this up and resist tracking more. Let's see how it works this time round.
