It's the internet. There's literally an "off topic" section in that white bar that's titled "CATEGORY ACTIVITY", do you not know what it's for? If you hate seeing them so much, then cry me a river, build a bridge, and GET OVER IT. That's like saying if I'm in class and the teacher is talking about math, then everyone starts talking about reading, then the teacher also starts talking about reading. IT MAKES NO SENSE.
