I deleted my Instagram app on my phone a few weeks ago because I was so sick of them showing ads for things that I did outside of Instagram. I started keeping track. I have a list of about 20 times they stalked my phone usage, here are a few: -Google searches from my laptop (like "Target") resulted in Instagram ads for Target the next day
-I used voice-to-text on my phone for IHOP and an hour later Instagram had an ad for IHOP.
-I had a phone calendar reminder with a link for Einstein Bros Bagels...a few hours later Instagram showed an ad for it.
-I sent Delta an online complaint and they emailed me. The next day, Instagram had a Delta ad.
-I use DraftKings app on my phone...Instagram had an ad.
-I ate crackers while watching TV...an hour later there was an ad for Wheat Thins. WTF - are they listening all the time?
-I texted a co-worker if they wanted KFC...Instagram showed ad for KFC.
Twitter does it, too. I opened a Word document on my laptop that included "Macy's" ...5 minutes later Twitter showed a Macy's ad on my phone.
