I have never had any problems with the advertisment here... except for those sound ones that were common here for a little bit not too long ago.
I hate popups with a passion. The reason I have a popup blocker is because I don't want to deal with them. They're annoying and I close them so fast I don't even look at them. I've stopped going to one of my favorite places to get lyrics because I have to close three popups with every link I click.
It's really starting to bug me on Newgrounds now, but it isn't like I'll stop coming here because I tend to get bored real quickly...
If there are hundreds of popup blockers and there are people who download Firefox for the built-in popup. I think Internet Explorer has a built-in popup blocker now. If it's obvious that people are tired of popup ads, why keep using them?
I don't click on any ads now, but if you remove the popups... I swear I'll click on them whenever I'm on the site. I rather have them come up as tabs instead of seperate windows...
