Lack of interest Email banning option

I find it very time consuming to add every email address that I want to add when I set up a new forum. It would be a lot easier if we could have an option to copy paste all of them at once or may be an option to upload and download a xml file with all the banned emails. This would also make it possible for different forum owners to pass such files around without much trouble.

This would also be useful when you have a bigger list on a busier forum and you want to use the same list on another one of your forums.

Instead of having individual fields for each email we could have a single fields with one address in one line.
