Tailored to the reader? For the last week, I've had a bra advert yet there is no woman using this computer, or, indeed, living here and I haven't posted anything related to, or containing any reference to bras, corsetry or lingerie. [Well, not from here or on this device !]
And I now get an offer for if I have a £250,000 portfolio. No hint of that in my posts, sadly.
