I hate to break this to you, they can do it already. The only thing to be added is the ability to prevent having to download the bytes that you are going to ignore anyway. For example, I completely ignore anything that comes from MurryMom and quite a few others.
Are you against people installing devices to filter out phone solicitors too?
I'm just anti-clique. The more heard from the better, while bouncing those who can't maintain a respectabkle manner for any length of time.
You reminded me about the best investment I made this year. I forgot about the Phone Zapper that blocks unwanted calls from those who call trying to sell me something and then sends them a signal that my line has been discontinued.
John Robinson's "kill switch" will be like my beloved Phone Zapper on Free Republic!
I probably will not block MurrayMom. Her innane threads and replies are great comic relief.
