One thing to note is that you are not alone with this feeling, in fact when I read your post it really remindend me of the song ‘I am Machine’ from Breaking Benjamin if you like Rock/Metal music.

I just don’t get what Google gains from allowing owners to delete reviews they don’t like so easily. I mean by doing this thy just strip away the worth of the review service since many shops etc. will have a 4-5 star rating even if they are in fact really bad.
