Designer: Can you hide scrollbar and still make web scrollable?
I: Sure.
Designer: Ok fine, i'll do that in next design.
I: Wait, how users will know the web has more content?
Designer: I'll put the mouse icon on the bottom.
I: It is not good idea. People can overlook it.
Designer: It will be fine.
I: I strongly recommend to you not to do it.
Designer: Why?
I: Confusion besides other reasons.
Designer: If you can do it, do it.
I: Ok than.
