No one had any idea to whom those posts and accounts belonged.
Since when is that a requirement?
There was no information in these posts that they were part of any school assignment.
Again, why should that be a requirement?
It is the first time that we have learned that you create something assignments like this.
So what? Just because you are ill-informed should make no difference.
BTW, I have informed Hivers about this in the past, such as here and here.
