I can no longer visit @YouTube due to a sponsored video (ad) in the sidebar with a shock image thumbnail. It's a tinnitus video intended to look like a heavily diseased ear packed with wax or pus. I clicked on it to block it, but there's no way, and now it constantly pops up.

Thanks. A graphic "shock site" image of a diseased body part seems okay by AdWords standards. I reported the video itself directly, and it appears to have stopped displaying.
Thanks. Twitter will use this to make your timeline better. UndoUndo
