Easier said than done. There is plenty of discussion in the archives about how 
difficult this would be technically. Because you can reject a key, but then 
what happens is it just keeps trying to come back. Pretty soon there are so 
many rejected keys floating around that the network stops reconciling. Also, 
what happens if I reject certain keys and you don’t, but your only connection 
to the rest of the network is through me? Once nodes start implementing 
different policies you can go split-brain surprisingly easily. 

It’s not a simple matter of just coding it up.
