I hate spam so much. An ungodly amount of hate. It sure does not help that current F/OSS’d spam-fighting techniques can’t keep up.
My idea? You know that little “Mark as Spam” button in gmail?
If you try and hit that on a post that came from a ML, it will offer to un-subscribe you from the list. Great if you’re stuck on a list, but it sucks if you want to be on it ( and it’s legit spam ).
Why not create an open API for Mailman ( and so on ) for whitelist’d entities to submit the “report”. If we have a shortage of data for spam-fighting, let’s get it!
