Although i rarely use feedback, why don't you can update/edit 5th feedback on every successful trades?
Although the new feedback system doesn’t have a feedback score and the old feedback doesn’t have any direct affect, I still think old feedbacks should be kept. Deleting them isn’t a good idea in my opinion. Why don’t forum increase this limit? Feedback spam can never be limited without manual processing.
In the old system, users were encouraged to keep the old feedback.
- Older ratings count for more, so don't delete old ratings if you can avoid it.
