It's just part of routine editing :) We not only catch vandalisms, but we can check grammar, typos, etc., or see how people have corrected our own mistakes.

The page of collected vandalisms is a great place for users w/o ban privileges to report "crime", assuming TWC's page is known and open to the public.
