Negative rating

according to mylot a - rating should be done only when response doesn't meets the required quality! so dont give a - rating to a discussion for simply the person has a fiffrent idea than you for example if a person starts a discussion that says about something that not in your interst ,dont give him a -.so (-) has some bad effect.it will cause your reputaion and earning

If someone leaves a response that offends me then i may be tempted to give them a negative rating. I don't know if we are supposed to do that but hey, it's my post. I think you shouldn't rate people things you don't want to be rated on the other hand, so I usually try to give a positive rating.

I think when the person responds something like "As if I care" or something like that. then you should rate it negative. But when the response is negative but is relevant to the discussion then you dont have to give them a negative rating. You just have to respect their opinions, after all we are entitled to our own opinions.

if someone posts are abusive or got nothing to do with what you have asked

you can rate -ve for abuse.
