This question already has an answer here:
It seems that some users tend to go on a reviewing spree and you see post after post by the same reviewer correcting the same thing in different answers.
For example, this one decided to add "highlighting" to several posts. This one decided that instances of "openSSL" must be changed to "OpenSSL" in several posts and caused quite a bit of approve-reject back and forth.
If it's not an option to limit reputation, better guidelines for reviewing are needed, and, a way to flag an editor for "serial-trivial-editing".
