I never harass telemarketers. Most of them are just people trying to figure out how to pay the bills and put food on the table on $10.50/ hr. just like most other folks.

If you really want to harass the people who deserve to be harassed, then find the home contact information for the company ownership and executive level staff and start flooding their e-mail and phone lines with junk. They're the ones earning six figure incomes shinning a seat with their asses while the poor sod they hired for shit wages to call you has to deal with your ire.

Before the don't call list existed I would let my 3 year old granddaughter talk to them. You couldn't understand a single thing she said most of the time but she loooooooooooooooooooooooved to talk on the phone.

It doesn't always work, but it's better than nothing.

By the way, I have worked for telemarketers who tell their employees NEVER to put them on a Do Not Call list. Yes, I know it's illegal, but a lot of them don't care. That's one of the many reasons why I refuse to work as a telemarketer now.
