That argument is pedantic and does not contribute positively to the discussion. Do you believe that the person talking about unsubscribe really means email from his mother-in-law?
Let's use our common sense, shall we? Do you think he marks as spam emails from his coworkers because they don't include unsubscribe links thar onl require one click?
If you don't think he meant that, let's not discuss it regardless of how one might twist his words out of context.
The person specifically said "any email that does not have a one-click unsubscribe". Two of the three categories I mentioned were not "emails from gramma" but that's the example you choose to focus on?
I really do think he means that he marks as spam messages that are not spam. And the biggest problem with spam prevention is the false marking as spam. It's much worse to miss a legit email than to receive spam.
> I really do think he means that he marks as spam messages that are not spam.
You honestly think I mark as spam receipts, emails I ask for, and email from friends? Did I really need to put the disclaimer in? I thought "While I'm not limiting spam to this definition," was enough.
Here, I'll help you.
Just to be clear, I also don't mark as spam email from my half-sisters, half-brothers, brother, sisters-in-law, brother-in-law, mother-in-law, father-in-law, step-mother, step-father, and my wife. Oh wait, forgot to mention all my cousins, and the rest of the family! Clearly, I must mark them as spam.
Not all email must include unsubscribe capabilities.
