That's incorrect and misleading. You do not need to initiate a send for someone to get your IP from a DCC connection..
If you initiate a send you will indeed be giving your IP out to the remote user over IRC-- however, if you accept a DCC SEND/CHAT request, you will be directly connecting to the remote host-- this is even more dangerous, as they can log the IP of the incoming connection and it will likely not be over the BNC/Tor proxy. The IRC network will not see your IP in this case but the remote user will.
