On some websites the ads are out of control. You get banners with loud music, and no way to disable it. Sometimes you go to a website to download something, and all you see is "download" buttons. You don't know which one to click. Some ads have bright flashing colors, or nude pics, things that distract you from the website content, or things that would make it embarrassing if someone saw you. Then there are some ads that actually give you viruses and malware. Even on youtube, sometimes you get a 30 second ad for a 16 second video. Plus you usually end up watching the same ad over and over again. If they didn't push ads so hard, there wouldn't be a need for adblock. They need to add some laws/regulation to ads, things like, not allowing flashing colors, loud music in banners. Not allowing misleading banners, etc.
