11. Feedbacks
False feedback for the Trader Feedback System is not allowed. Feedback is also meant to be unique. This means that a single user can not give the same user multiple feedback in an unjust way to abuse the system. An example of this is buying/selling back to the same person over and over or trading in small increments and counting them as separate feedback. This can result in a full feedback reset or a ban.
It is allowed to receive feedback for a service, as long as the service was either paid or there was risk involved. An example for risk is doing a firecape service for someone, on an account that contains more than 1M RS3 GP or 07 GP. As we are aimed particularly at the RuneScape market, you are only allowed to give or receive feedback for graphics if there is at least $1 worth of goods (based off of common transfer rates) transacted. Feedback for free product will not be allowed. For further clarification on this rule, read here http://osbot.org/forum/topic/47264-feedback-rule-change/
If you use a middleman you may give him feedback but the middleman himself is not allowed to give feedback.
From the rules I was slightly wrong aslong as some risk was invloved so I guess as they are trusting you with there accounts they would be allowed to give feedback
