Yep me too. Wife was adamant her phone was spying on her so we decided to test it by talking about Lexus cars (having chosen cars because at the time she was getting no car ads anywhere, had no interest in cars, and she had never heard of the brand before so certainly hadn’t searched for it). A few hours later, her Facebook feed was full of Lexus ads. 100%.
Nah.
