malformed. But when I add the offending IP address to my blocked list, they 
still show up as malformed upon subsequent readings of access.log. That is, it 
appears to me that nginx isn't checking the blocked list first.

It's unclear what do you mean by "my blocked list".  But if you're
speaking about "ngx_http_access_module" then the answer is no, it
shouldn't take precedence.  It works on a location basis, which
implies that the request has been parsed already.
