I think all of these big companies lack a meaningful feedback loop from reasonably vetted people, lending credibility to their feedback. Most of them don't provide the tools to diagnose, nor have the ability to receive support requests. Not just SPAM, but all kinds of sanitation type services.
I know people at the large mail providers and I have to have some sympathy for them. They have mailers endlessly screaming at them, outraged that the Valuable Offers from their Treasured Marketing Partners go into the spam folder or worse, and they're sure that someone manually made that filtering decision and just has to flip a switch to fix it. Vetting trusted reporters just doesn't scale. To repeat a cliche, any group large enough to be interesting is going to include people who shouldn't be there. R's, John
