Thanks for pointing that out, I had briefly wondered what the ebs in ".ebs-container" meant.

Now that I've blocked it with CSS, I hope they don't ever have anything important to say. It's a shame they decided to misuse it. (I also block #WikiaNotifications, as that is used more often for spam than important information.)

I would also turn off my Emergency alert system if it started auto-playing commercials at me.
