I feel like robot calls used to be much more common. I think I only get maybe 2-3 a year now. I think most recently they were from DirecTV and GNC. I tend to give out my Google Voice phone number to businesses and non personal contacts so I can block them if they sell my number or start robo calling it. Although I've only had to block maybe 1 or 2 numbers on google voice in the last few years. I wish the iphone had a way to create a black list and block callers. I'm not sure why they've never implemented this. I know it can be done by jailbreaking but it seems like it should be part of the os.
