I use an adblocker and do not see any ads on Tapatalk. If I didn't have an adblocker, I'd probably get fed up and would stay off the internet entirely--which probably isn't a bad idea!
FitBoop, privacy is a huge concern. I was having a phone conversation with a friend about her husband's medical issues and not long after that, I started getting ads on Facebook related to what we were discussing. Creepy. My adblocker doesn't work on Facebook too well for some reason so that's the only place I see ads.
