I just got personal email from someone at Uber. They explained to me that they comply with Can Spam by... providing unsubscribe link. Nothing mentioned how I got on their list in the first place, on what their practice are. Clearly my email must have been scrapped from public sites, since I never did sign with them in the first place. So yeah if they don't even know the rules of Can Spam, how the heck you expect them to follow the law? I will have a short call with Attorney General in my State end of this week to see if I am a separate incident.
