Same reason why you should report spam to SpamCop: help clean up the internet, and clamp down on spammers so others don't have to deal with them?
Especially when the originating server specifically has a policy of not allowing outbound spam.
I don't see why she should defame GoDaddy. If I had a server there, and I was accused of sending spam, I would have the right to know which address considered my email as spam (and determine for myself whether the user subscribed to my services or not).
GoDaddy deserved every last ounce of negative coverage for this they can get.
Generally, when someone gets too many spam complaints, or doesn't handle them well, they get terminated from the hosting provider.

I didn't mean to imply that was what happened. I said that they'd have to if it's to be checked.
My thoughts were that you're either going to have to trust the accused spammer - in which case you can turn over the SHA of the complaining email address, and the provider can compare it to the SHA hashes of their own. Or... they're going to have to turn the list (again, preferably with the entries hashed) over to you - and then, I suppose, you'll have to trust that they're giving you a truthful list.
But, either way, I don't see how the mere act of hashing the list is going to significantly alter the problems of nuisance complaints or of dealing with large lists. Hashing is a very cheap thing to do after all.
The problem is the 'Report Spam' button is also the 'I no longer wish to receive this email' button to non-technical users. Just because you've received a spam complaint, doesn't mean that it wasn't an opt-in email.
Providers never attempt to verify your email list. If you generate too many spam complaints, you get terminated. It's not feasible for a third party to get a copy of your mailing list, then somehow evaluate how legitimate it is.
This and that are not exclusive.

Because they shared personal information with a complainee? If you go to the cops and make a complaint, would you find it normal that the cops go to that person and immediately give them your name and address?
> I would have the right to know which address considered my email as spam
Now consider that from the POV that your are a spammer and acting in bad faith, you've just been handed the keys to retribution, that sounds absolutely wonderful does it not?
That is false for any value of yyy.
You don't need the email address to defend yourself (which is ok), you only need it to retaliate (which is not ok).
It seemed to be a comment drawing an analogy to the criminal legal process. And in the US, that process guarantees you the right to know what you're accused of, why you're accused of it, and to confront the people accusing you.
Only the latter being at issue here, and in criminal proceeding it's done through cross-examination during criminal trial, not by giving the witness's address to the accused.
For example, if someone sues you for spamming (under some theoretical law which would allow that), you'd be able to know who they were and get information from/about them during discovery.
