 I know. You get a message from some politician's campaign. They want some money. You ignore it. You text unsubscribe or stop. And then the messages still just keep coming and coming. So annoying. Now, many legit companies offer you a chance to opt out. But you have to be careful because scammers are now using the same technique to lure you into replying stop to their messages, which will help verify that you and your number actually exist.
