Over the last few days, I've noticed an ad that appears on the right rail of an individual board, and after the first post on a new page of a thread that prevents me from scrolling. The ad essentially anchors you to it and you can't scroll past it without x'ing out. Not sure if it's related, but it also seems the add prevents you from typing in the reply box. I start typing, but the cursor disappears and I have to click back into the input to be able to type again, only to have it continue to do that until the ad disables itself. ...Ugh.
