Yeah, gotta consider multi-modal interactions... and also there's no good way to pre-validate ownership of a phone number. So suppose Carol clicks "Contact Me Immediately Please" on a website and and enters her phone number... But--oops--there's a typo. Now Alice is going to get an "unsolicited" message even though literally everybody involved is operating in good faith. Even if someone is maliciously pretending to be Alice, neither the website nor the phone-carrier has a better malice-detecting tool than simply sending it and seeing if the recipient replies "STOP". |

I sometimes wonder how many people use the STOP function. I'm more inclined to ignore it (if it's a one-off) or use the spam reporting feature than I am to reply "STOP" if I don't recognize the sender/campaign because of how jaded I've gotten from email. If you hit the "unsubscribe" link on a spam email, you only get more spam because you just confirmed the inbox is a) active, b) monitored, and c) is checked by someone willing to open and interact with spam messages.
By the time SMS spam became common, I just assumed things would play out the same, and have probably reported plenty of legitimate mistypes to Verizon as spam. It just doesn't feel like it's worth the risk to directly respond.
