Yeah, don't think we should have pop-up ads. If you do get any, then I think you're supposed to report them because it means they snuck through. We'll get the normal ads back early next month because I turned off the renewal for it.
Hm... I may have had a potentially malicious ad. I opened my browser and usually I restore my session, but instead of being taken to the site directly it took me to a page telling me to install something. Please do not agree to anything like that if you see it. Just leave the page immediately! I know most already know to be cautious and safe against such things, but this is more for anyone who is not as aware.
