As for the B10 and SEC, I don't recall but not sure and even if you don't see it who cares? Not like they are make the rules.

They do want everyone to think they are better than everyone else, and on the field they have been but that doesn't mean if they don't it isn't cool.

I have seen it used against other teams, just can't recall what games. I will start to pay attention when I do and post on here for you.
