Pretty much what it says on the tin: while a reviewer is blocked, the "review this version" dialogue still comes up, and you can set the flags and comments as normal. You even get a "review complete!" message when you click the 'submit' button. But the review fails silently, and is not recorded as successful (or unsuccessful) anywhere.
