That could explain why I've been getting oddly accurate (highly targeted) ads on FB related to the niche of a new app I'm developing. I haven't liked similar stuff on FB and I was wondering how in the world FB knows that info (I have talked about it extensively via whatsapp). So there are only 2 options:
1- They somewhat are able to read my browser history even when I have ABP with "Fanboy's Social Blocking List" and a selective JS blocker installed.
It is more likely that you visited a site with 'Facebook social integration' on it.
>"When a logged-in Facebook user visits a site with Facebook social plug-ins, Facebook receives the Facebook ID and browser ID, along with the URL of the page being visited,"
How would they link your whatsapp account to your facebook account? Whatsapp only knows my phone number and what phone numbers I contact, and my facebook account doesn't know my whatsapp phone number.
