Can you imagine just how many people may have two accounts here; one 'normal' account for honest discussions and debates (when they can be bothered) and then another one to spread rumours and gossip, hurt, fight, and what might be even worst, back-up their own bad opinions put forward under their regular username. Fortunately they are usually not smart enough to work on their hide though, spelling often uncovers them for instance.
I won't be naming any usernames here, but those who have been members here longer than a day will instantly know who I'm talking about.
