I had someone contact me on Kijiji yesterday about a seeing machine ad. We exchanged messages 7 times in total. But 4 days ago 160 tracking attempts by 6 companies were blocked in my Kijiji app by Duckduckgo. I can't remember using my Kijiji app 4 days ago except to repost an add that was about to expire and Kijiji wouldn't repost it for me.
