It is a bad idea to send any kind of money to anyone without first asking for a signed message confirming the address to send to as well as the terms of the trade.
On the subject of quoting a message -- it is generally pointless to do so if you are not somehow relying on said signed message because there is nothing to stop you from editing what was posted after you click the "quote" button but before actually posting.
