RE: AskSteemit: What was that Facebook suggestion that made you wonder "how did it know?"?
That was when I joined Steemit!
I didn't use Facebook much last year, and I didn't use it at all around November and December. In January, I joined Steemit. Then I met some people and started using Facebook more because I had to organise some communities for content-creation for Steemit and Steemit-related people.
When I used it again in the first week of January, the first thing I saw was a Steemit post ad. Someone had promoted their post and Facebook had thought that it was relevant to me. I shared the screenshot around and haven't ever seen Facebook with the same eyes as before.
I mean, I didn't even mention Steemit because it was my "secret project". Only people I talk to on Telegram knew of this at that moment. I don't even know what led them on it. Is some Steemit service selling info? Are they listening to my devices?
I haven't heard of any Steemit services selling info yet.
Steemit/Busy.org and other Steem apps already have lots of tracking scripts following users so it should not be a surprise that info will leaked to Facebook and others.
See this screen of all the scripts on a random Busy post:
