We've made it pretty clear the alterations to the bounce, and I see no reason to change this

OK, I understand. I have a complete different opinion on automatic bounce. cleverly and smart programmed, it is still one of the best leverages the user has to stop spam.
To reach this goal you have to mimic a "mail not delivered" message, which is not obviously recognizable within a minute. And which is only good for a laugh, as you mentioned....
You cannot carelesly program this message, and then use it as an argument that this feature will not work.
Your other argument, that 99% of the return adresses are fake:
1. where did you get that number from? I have a number, that most of the return adresses are either missing or working (the spammer wants to sell something, so he has to deliver an adress)
2. If the spammers sends millions of spams with flase return adress, then they will never know, which adresses are still valid. so i assume they will have at least 10% non existing adresses in their file. So "innocent bystanders" will automatically get "thousands" of return mails, simply by email provider who just do their job. The bouncings of some MW users will not add much to this load.
3. Companies who buy email adresses for spamming are not buyíng "dead adresses". so somehow and somewhen these adresses will be tested with a real return adress. And if they get thousands of returned "not available" adresses, they will automatically erase them from their file. The MW bouncings included. mission completeted...
But it depends on the fact, that the return mail you create isnt obviously sloppy programed.
So if you want to leave this very promising and working field of activity, you open up the way for a new entrepreneur company, who is willing and able to sell a smart bounce-mail spamfilter, which i will be very happy to buy.
I do not need another drag&erase spam-program. This I already get from other companys, mostly for free. Even from my email provider.
Please excuse my bad english..
