I'm sure there's an excellent reason why these addresses stay blocked, but am unable to fathom what exactly that is...
If I'm a smaller shop with limited clue, there's 3 likely colloraries: 1) Even a smallish spam blast is big enough to cause me operational difficulties, so I'm tempted to throw in a block to "fix" it. 2) Once the spammers have moved on, it's unlikely that I have enough customers trying to reach the blocked address space and complaining for me to fix it, and the people *in* that address space can't successfully complain because I've blocked it. 3) The damage to traffic is of consequence to the remote site, but isn't a revenue-impacting issue for *ME*. The third point is the biggie here.
