This is why I love FR. You can click a thread and never see a pop up. Yet when some one links to a source, and you click the link and are inundated with ads and pop-ups, you have no choice but to close the link and go back to the thread.
When that happens, we should click report abuse. We need to start alerting the moderators to start deleting threads that link to useless and unreadable sources.
A lot of FReepers have browsers and add-ons configured properly to avoid the problems you have.
