Today I got a call from 1 800 816 3521 and chose not to answer. They left no number. So I googled.
The site that had something that looked the most authentic was everycall.us. It had this chart and then comments below.
The everycall site offers a device to block such calls from your home phone. I have no idea who they are or how legit they are. They have a Kickstarter campaign at the moment with a picture of a little white box that says:
"Plug into your home phone and those pesky telemarketing and robocalls just stop. The 1st crowd sourced spam blocker for the home."Kickstarter does screen the people that use them, so there was at least one level of scrutiny. they have raised - as of today - $5,361 out of a target of $100,000. There a Bellvue, Washington company, so they are in the heart of Techland, USA.
There's a small industry popping up on the net to help people find out who is generating the annoying calls that come from 800 numbers. Here are a couple of the websites where people leave comments about 1 800 816 3521:
I've previously posted about 1 800 695 6950. There I was able to find out it was a collection agency. I also posted a link there to the Do Not Call registry. But that doesn't work for political calls. And I'm not sure I want to block political calls. I have to think through the free speech implications more. But there is a website where people are trying to block political calls at home with a registry. It says on there:
Join the National Political Do Not Contact Registry a non-partisan grass-roots movement to take control back by asking our elected representatives to stop calling us at home.Yeah, I can see them setting up the registry, but I can't imagine too many legislators limiting their right to call you at home.
