I have only received one negative point and it came with a pretty offensive comment as well (and without a signature, of course
). This irked me somewhat, especially as the post which prompted this proverbial assault was really a nothing post in which I criticised the Departure of Denethor in the film.
I would argue that it is bad form to negative-ise someone without leaving a comment as well as your screenname. It's not a playground, we should be able to deal with differences easily here.
