Question: What do you do about people who leave unjustified bad feedback? I'm talking about the new star system on the site, not on the reputation threads.

I recently had a guy hire my rig for only 2 hours. The pool he was using went down a couple of times, and he's left bad feedback because he thinks it's my fault. I even explained it to him, yet I get 3 stars only for communication.

If this was eBay, I'd be able to challenge the feedback and have unjustified feedback removed. What's the situation here? I'd like to know, because anything less than 5 stars puts potential customers off.
