Is use of tools and extensions such as AdBlock for Firefox and OperaAdFilter unethical? I was recently banned from a very popular forum just because I used a filter to block the ads that used to pop up on the forum. I know that these ads are the only way that these forums can run, and without them, the internet wouldn't really exist, but isn't this upto me to decide whether I want to see a these ads or not? Some of these ads are really irritating. They keep popping up when you're doing your work. I want your opinion. What do you guys think?
