Why don't you use your brain before you flame?

If the tracker has no IPv6 access, it cannot accept incoming connections 
from an IPv6 address to verify that address, nor can it connect back to 
a peer claiming to be at an IPv6 address.  Therefore it would have to 
assume that peer was telling the truth about its being at that address.  
A peer could therefore insert a bogus address, causing the tracker to 
direct its peers to attempt to establish connections to that address.  
In the case of a large swarm, this might cause problems with a server at 
that address.  This is called a DDoS.  Got it?
