I cannot see what you see on that specific one so I went looking. On Sports.SE I have a few tags I like to avoid, which means I see the Questions list like this: [![enter image description here][1]][1] If this is what you are seeing then it is because of your Ignored Tags list. Can you guess what mine are on Sports? :-) If however you see yellow colour coding, like this: [![enter image description here][2]][2] Then it is from having a gold badge for that tag. (Earn at least 1000 total score for at least 200 non-community wiki answers in the tag) And if you see pink colour coding, that indicates deleted posts - you have enough rep to see them. I'm not going to copy any up here, but they should be obvious. [1]: https://i.sstatic.net/No5iY.png [2]: https://i.sstatic.net/LKOpZ.png
