I can only agree with the article. Also jumping through the hoops of BigMail, which is nothing more than BigSurveillance, but often find that emails are just disappearing. But since a fari amount of emails are delivered to (say) Gmail, I don't think it is blacklists.
I am starting to think it is AI algorithms that no one understands what they do, only see that a lot of the spam is reduced, without knowing how much false positives are filtered out as well.
