I do agree here that using fake addressing and so on is really bad on 
many levels.  I know on one of the networks I was involved in recently 
we had a customer who was a spammer and I pulled his services very 
quickly, some might even say to quickly.  I also realize that even 
though I personally don't find it to bad to to deal with others don't 
agree so like I stated my professional policy differs from what I do 
personally.
