I win another dubious achievement award for being the first to receive a call from these spammers or scammers. They called my cell. They were blocked. Forever. They will undoubtedly call back under yet another number.

Here's a compelling reason why we should continue to send these numbers to the Do Not Call list: There are certain apps that block numbers on your cell phones, and others that block on your home phones. They coordinate with "known spammer lists," e.g. the Do Not Call list. So by all means, keep reporting the numbers!
