Adblock Plus have announced that
they will start serving ads over top of the ads that are being blocked by it. In other words, they are stealing ad space from the sites you visit.
My recommendation has always been to whitelist the sites you normally visit if their ads aren't intrusive. A couple banners here and there don't present much of a problem. Here at RS we don't run popups or video ads. Just images and text that don't cover the main content.
In any case, if you run Adblock Plus you should immediately uninstall it and use something else instead. I'm sure someone can offer some suggestions of some non-sketchy non-thieving ad block plugins.
No matter what you do, please consider whitelisting RS which helps support the site. In fact, I have found banners that run here to be quite useful! For instance I totally forgot about the Warcraft movie opening date, but a banner notified me of it the day before. Another time, I saw a banner for an Under Armor seasonal sale which I never would have known about otherwise. I was able to pick up some gear at a good discount, thanks to that ad!
