Ahh so you’re oblivious and don’t realize you’re watching ads. Not sure if that’s a good thing.

I run ad blockers on everything, at a software and network level and still see ads from time to time. Let alone my friend posting on social media how great a product is they’re sponsored to promote which is an ad.

You can block a majority of them but it’s impossible to block them all, and you’re delirious if you think you have unless you severely restrict your interactions with Internet-connected services or have spent days tinkering/blocking out most content.
