Well, on AG I don't see one single ad. I rarely see ads anywhere. There are ways to tweak your browser and have a few programs running in the background to eliminate them.
I have only ever encountered one variety of intrusive advertisement on AG, and it no longer pops up. All the ads here stay in their place and they're harmless banners. I've encountered many of the aforementioned ads on other websites, not AG.
why can't they just find a better way of advertising instead of forcing people to actually view the ads
