A report to the mailstore operator need not be more than a few bits. I'd 
advocate at least two bits ("block" and "report"). But the value of the 
reports lies in crowd-sourcing them.

It's a concern for users on low bandwidth connections. For example, my most 
frequent general complaints about spam volume come from people working in 
the field in countries with poor infrastructure. They want the most 
efficient access to mail that they can get. That means NOT downloading 
messages that they want to report as junk.

We're also seeing significant use of mobile devices for email - mostly 
iPhones at the moment. We expect to see that increasing.

Certainly the people with most incentive to report junk, are the ones with 
highest volumes of junk, and lowest bandwidth access.
