Know it? It's a pay service to stop spam calls, telemarketers, etc. I shut it off because I had a very important call coming in but didn't number number they'd be calling from.

Been running RoboKiller for... ohhh, I guess a couple of years now. Maybe three. And it works. I never get telemarketer calls.... and I figured that by now, after 2 or 3 years, my number had been removed from their database. I was wrong.... one day shutting down RoboKiller and the spam crap began. Got about 6 before noon..... when I received my call so I could turn RoboKiller back on... and no BS calls since firing it up again.

Want a conspiracy theory? They could stop that crap.... they don't because... that's right, they're making money leaving it be. - JamesJM
