There shouldn't be any popup ads being served by the site.
Google is allowed to place ads on the site, but they should be banner ads scattered through the site.
I try my best to strike a balance that has the site make some money as a business, but turn down some of the higher paying ad types that would IMO cross over into being annoying. Popups would be an example of something I dont want to see. eg the type of ad that sits on top of content that you have to close before you see the content.
There was a time that Google automatically conducted an experiment with an annoying type of ad on 5% of site visits just to show me how much more it could generate, but once I found out about it I said thanks but no thanks. Its also possible that software running on a person's own computer that I have no control over is serving ads. Can you post a screen capture of what you're seeing, or email one to me at adam (-AT-) ebrandon.ca so I can figure out what's up?
