Anything that tries to hide the unsubscribe link or makes it especially difficult to unsubscribe, not only gets unsubscribed from, but also gets marked as spam

Anything that tries to hide the unsubscribe link or makes it especially difficult to unsubscribe, not only gets unsubscribed from, but also gets marked as spam by me in Gmail. I'm guessing that not only does Gmail filter spam by content heuristics (dick pills, Nigerian princes, etc) but also considers the number of times a sender has been reported as sending spam by users. I'm putting out hope that by clicking that spam button, the sender gets closer to being marked as a spammer for everyone. The one great thing about email is that your email provider isn't paid for delivering spam to your inbox unlike the USPS. There's zero incentive for Gmail to deliver anything but legitimate emails from responsible senders whereas the USPS will gladly deliver presorted mail because they've been paid to do so. I kind of wish I could pay USPS to not deliver junk mail.
