I have a website with some adsense ads (that pay for the server). I try blocking the most obvious scams by blocking the announcers but it's basically impossible because the same dodgy ones keep coming back with a new name. Also hard because they're not always in a language you understand. I don't think I should do all this work instead of the biggest ad company in the world just to earn 5€ per day, but I'm also not aware of any better alternative.
