In yesterday's world anyone could send a physical letter to any address 
anywhere in the world. I get spam letters through the letter box it is up to 
me to chuck them in the bin. Why should the internet be different especially 
when the restrictions on fixed IPs are brought about soleley for commercial 

If the same protocol was applied to physical mail then we would not have been 
allowed to send letters unless we had a big building to send it from and all 
letters would have had to have had a "big building" sending address.

No banning on the grounds of address type is discriminations. Yes bad because 
there has been specific abuse and ban until the abuse is cleaned up.. but do 
not ban on type of address!!

It would be like saying only the rich could send letters!!
