Sorry I have to agree with Steve as well. I know I've left networks with 
Bogon lists in place and then gotten calls a year or more later asking why 
traffic can't isn't coming in from XYZ new client. Turns out the new admin 
never updated the bogon list.

If this was done through a central repository and updated daily, or 
required the list to be refreshed periodically otherwise it timed out- 
fine. The problem is people leave these lists in and forget about them.

If you are going to keep on top of them, and make sure to remove them when 
you leave- then that's great. But if you are going to do it half way- 
please don't bother.
