Cliffs: The Do Not Call list doesn't do much to stop robocalls. This is because there's plenty of people willing to just break the law, and it's very hard to catch them. The DNC list doesn't actually block numbers from being called, telemarketers are just supposed to police themselves. And if somebody calls you and you're on the DNC list, you can file a complaint. But that's unlikely to do anything. Most robo-callers are using spoofed numbers, so you don't actually know who's calling you. But even if you did, all the FTC can do is slap them with a huge fine ($11,000 per unauthorized call). But if the robocaller doesn't have the means to pay... oh well. In 2009 the FTC dished out $330 million in penalties for companies that broke Do Not Call rules. But they only collected $19 million. The rest were smaller operations that just folded their operations, a new operation popped up doing the same thing.

There needs to be stricter penalties for calling somebody on the Do Not Call list repeatedly, including jail time. Not just 'fines', which do nothing.
