Mystery callers

The home phone still gets a lot of telemarketing calls, mostly from the phone company and the credit card companies we deal with. On the caller ID they usually show up as a toll free number without any name associated with it. We hardly ever answer the home phone anymore anyway.

Today I thought I'd run a few of the numbers through Google to see what came up. Stumbled on a very interesting site,, that tracks all kinds of numbers that people submit, and allows people to comment on the numbers. The top of the web page says

The phone is ringing, and I don't recognize the number,
All Caller ID says is, "NAME UNAVAILABLE".
Please help me figure out who is calling and what they want

The home page has a list of phone numbers ranked by the number of calls, number of comments and the states that were called most. You just enter the phone number and up comes a list of dates that people reported a call from that number. Usually one of the comments will provide a clue as to who the caller might have been. There's also a Google Map showing where calls were reported from.

Kind of an interesting site, but there's no indication of who's behind it or any other 'About Us'/'About this' type of information.
