You propose to ban double ending but if double ending is banned the «scumbag
agents» (as you refer to them as below) will simply refer the buyer to another
agent for a
few hundred dollars and then disclose the contents of other offers to that
agent, so banning double ending won't change anything other than preventing consumers from being «allowed» to deal with the listing
agent whom they may know and trust and / or feel that
agent knows more about the property or area than other
agent and «force» the consumer to choose another
agent who they may not know or whom may not be as
knowledgeable about that property.
