Hi Junxiao, then:

No attacks in particular, it was just a stupid example in order to  
explain if the operation of calling onInterestFinalize was possible  
locally in an NFD :)

Assumption, like above :) The example was very stupid just to explain  
better the feasibility of "remove an interest from the PIT without  
satisfy it with nack or data"

If we focus on this example, just modifying the code of all the NFD  
inside an institution :)

Probably a better example helps better to express my question.
I am Jon and I know that Peter is my enemy. I don't want to receive  
anything from him. Jon offers services public in the world, but for  
his reason he doesn t want to perform this service to Peter. Jon  
desire to remove the Peter Interests as soon as possible without  
satisfy them neither with a data or nack. The PIT table has just space  
for 3 interests pending per time, then It is suitable do not occupy  
it. Jon could modify its NFD in order to do:
if the interest received is from Peter then
remove it by my PIT
Thanks a lot,
Matteo :)
