In addition to blocking email, I also subscribed to Robo-Killer - primarily to divert the GOPe solicitors and other spam callers.
It is hilarious. Your phone doesn't ring, but diverts the call to a recorded/staged "sceanrio" then they send you a recording of it. One is a Russian call taker, one pretends it is Area 51, and other is an annoyed female who is being called out of a movie theater. It is quite entertaining.
I see the GOPe tries to bust through Robo-Killer using various phone lines, but so far-so-good not talking to them.
In one argument when Sen Dick Turban (Dumb-IL) was running, I asked the the GOPe caller who the Illinois Republican candidate was, and they couldn't name the candidate.
I presume 'Robo-Killer' is an app for a smart phone and won't work on my cranking wall phone.
