I realized that Facebook was almost certainly spying on my texts when a friend sent me a text mentioning The Big Bang Theory sitcom, something I never watch and have never previously mentioned in any digital communication. When I logged onto Facebook the next day an ad came up for The Big Bang Theory, which I've never seen an ad for before. I've now deleted Facebook from my phone.
Earlier today I texted a friend a photo of sanitary towels, as she had very kindly said she would get some for me while at the supermarket, and I was showing her what type I wanted. Then this evening I logged onto my yahoo email and immediately saw an advert for Thinx knickers, saying "Period proof underwear". I don't know whether it's just coincidence or whether yahoo is spying on my texts. Has anyone else had anything like this happen?
