Occasionally I see in the suggested edits section that someone made an edit that completely revises the whole build and writing style of the OP (whether it's a question or an answer). It's not just adding sources or correcting spelling; sometimes it could come out to doubling or tripling the length of the post, completely or almost completely erasing the personal style of the OP. That never seemed to me quite right. If the question makes sense, why "write-off" (pun unintended) the OP, so to speak?
Anyway, I was more wondering what others think of this and/or if there's some sort of policy on this.
