While it's true that one of the reasons this site exists is to let others know "who" is calling, it's also true that it exists to try and "gauge" the number of calls from a particular number. There's nothing wrong with a post saying "I got a call from this number" if they chose not to answer it.
Received call when not home Saw number on caller ID. Tried to call number and says the number is a non working number. Had these before and when tried to call back to tell not to call me anymore, no body answers or says non working number. Whats up with the DoNotCall List? I have been on it and still get a bunch of calls a day. But now they are non working numbers or dead air on the other end of line or someone answers and immediately hangs up. Go figure.
