Unwanted calls fall into one of the following 1. Outright fraudulent. 2. Unintentionally fraudulent. 3. Legitimate but abusive. 4. Legitimate but useful. The first will change telephone numbers often. 2/3 will seldom change numbers but there is a lot of them. 4 you want to get them. Black listed numbers won't help for 1. Black listing for 2/3 won't help unless one number repeatedly calls. Obviously you wouldn't want to black list 4. White listing won't help if you want 4.

Cursing at them doesn't work. Phone carriers are useless.
In the US there are various ways to deal with this. You put your number on do not call lists. You can file written complaints. You can sue at least in some jurisdictions. A least in some cases it is small claims court which telemarketers would be loath to fight since it is local to the consumer not the telemarketer. http://www.npr.org/templates/story/story.php?storyId=7532224[^]

I am not a mobile device programmer, though I feel certain that I might be able to bulldoze my way through building an app - though it wouldn't look pretty, and there would be some serious doubt about the functionality of it. So, I am looking to you (the development community) to help create a solution.
They already exist.
