FYI, if you see a lot of these we can review and suspend a user from approving edits. It's a real pain to do, and it discourages involvement, but with a big enough list of badly approved edits we can look through them and see if a user should be banned from approving edits. I would personally only do it if the same user approved at least 2 really bad edits within a fairly short period of time, but it is an option.
For the edits from that particular user, there were 2 poor edits suggested and 4 different users who approved the edit, so far as I can tell. Hats off to the one user who rejected one of the bad edits!
