When I hear someone mention they were banned my reaction is: "Holy shit! WTF did you do to earn that!" Then I find out it was only for a day or three: "Oh... That's not a Ban! That's minor. Go touch grass. You'll be fine."
I've been banned from subreddits and communities a few times. At least once I never even noticed because it was so short.
How is it a Ban if I didn't even notice?
Why did Ban in online forums and games, come to mean temporary?
Is it simply an example of the intensification of language? To make something mundane, seem more severe than it is?
You're missing the point. I'm saying that there are contrived situations where there are privileges that are not access that you could suspend without the word "ban" making sense.
Any case where you block access to anything for any length of time can correctly be defined as a ban.
A test that punishes a correct answer is wrong, and yes, it's entirely reasonable and not uncommon to have multiple valid answers that are accepted, or for a decent teacher to have a student point out "this answer was right" and allow anyone else who gave the same answer to get the points back as well.
