I'd even consider these edits harmful. They are using quotes to highlight random paragraphs which are not remotely quotes.
What to do in such a case? Flag one of the answers/questions for moderator attention and mention that this particular user is vandalizinvandalizing in their edits. You don't need to include a whole list of edits, the moderators can see the edit history for any user.
I rolled back the edits. Please be more careful when reviewing, if you read this:
