Adblocker doesn't remove the banner. I personally would rather see it on the bottom when normally browsing the forums.
May not remove it by default, but can sure be trained to ignore it, just right click it and "mark as ad/spam" (at least that's how my plugin works).
Id rather not block it as I do like the idea of it, it gives your fellow players a place to advertise their shops and events, I would just like it to be less intrusive. Would you like it if I blocked a honest ad for your shop?
