I blocked a buyer who was making really low offers on my items. They have since created new accounts and bought the same items which I have to keep cancelling as I foresee issues. I have now reported them four times for this and ebay are saying they are not violating any policies. I don't want them having my contact details or making claims against me but I have now had to put my account on Time Away as Ebay won't do anything and three cancelled orders in the space of an hour is bound to have a negative effect on me.
