Upvotes and downvotes on ads are just cosmetic, they don't do anything.
It hurts their feelings, sometimes that’s enough
Anything but. They'll be using that feedback to profile you, to better target ads at people like you. It's like Facebook's "I want to see less ads like this". It's to give an appearance of control. But really it implicitly means "show me more of what I didn't reject". Even if you're there anonymously they'll be associating any interaction you make with the ad with the subs you visit, the types of comment you make etc
