Just to balance the concept, usually people who have maintained good ratings for a long time, don't do this. I have worked for like 5-6 years at odesk part time, done around 40 jobs of varied sizes (hourly as well as fixed prices), never even once held back code or any thing, and barely once received some what negative feedback in which case i believe it was still my fault. So all sorts of people exist and work online. Those who have build reputations over years value it far more than the money, and an employer can easily trash the reputation with feedback. That being said employers from the western world are generally nice or may be it was just my experience :)
