Right, by "default" I was referring to a default minimum size block assigned to 
a particular product (I would guess this would normally be in the range of /29 
to /27).  I understand justification would be required (I hope), but I was 
thinking of this from the perspective of trying to put the onus on the 
customer's to have an incentive for using their provider assigned blocks in the 
most efficient way.

I understand this, but if said SP is doing this for spammers, they are likely 
not getting paid and only ending up with dirty blocks that nobody wants.

Please understand I am discussing this based on the assumption that the 
additional addresses are justified by a non-spammer customer who really needs 
more space. 

I am open to the idea that charging for address space is a non-issue due to the 
spammer issue mentioned above, but could you please elaborate?  Is it just 
common practice to never charge by most SPs?
