I see there are 3 negative feedback tonight and it appears none of them actually relate to a shoot that was ever arranged. Surely this can't be right. Just because someone doesn't communicate with you, that doesn't entitle you to leave negative feedback.
If a photographer were to offer £30ph and a model declines to work with them surely that is no reason for negative feedback, or maybe it would be if it were the model complaining about unacceptable approaches.
