I get emails for some dude's Chevy when it needs servicing. I can't unsubscribe. I am stuck getting emails about a car I have never owned from some dealer in Pittsburg. I need an opt out that lets me communocate "hey, some dumbass fatfingered his email, stop spamming me."
I'm honestly curious.
I think what you're picking up on, is that some folks don't differentiate between commercial email filtering services, and personal spam filters.
There's conflation of email 'I don't care about and don't want', bulk UCE, shifty list operators with shifty 40 page terms, etc.
1. Some senders intentionally send ads and actually useful notifications from the same address, making filtering more difficult
2. Better yet, some senders constantly shift their address so they are almost unblockable without going to arbitrary keyword blocking
I would like to live in a world where instead of me doing stupid amounts of work to not get a flood of spam.. people just don't spam.
I am lucky - I can literally throw money and tech at this problem. Most people are not lucky. I would much rather spam be elimited as a whole.
