TFA says "uploaded" multiple times. Doesn't it seem like advertisers would download (not upload) your info from Facebook?
AFAIK, one of the advertising method available on facebook is that advertisers can upload a list of contact info (phone numbers, email addresses) to facebook, and facebook will match these info to their corresponding accounts, and voila, ads are served to you. I remember this when I review what facebook has on me, and they showed me which advertisers has my email address and upload them to facebook
