I've been thinking about running my own in-home PBX to deal with this, too.
Whitelisted numbers, friends, family, and businesses I want to talk to: Rings right through.
Numbers not on the whitelist: straight to voicemail, my phone does not ring, not even once. The voicemail says, "Hello?" a few times to see if anyone answers, then says "This is a recording, please leave a message" in order to (presumably) get the robo-calls routed to an actual agent.
Numbers on the blacklist: Forwarded to Lenny, or something very special I program myself. (I don't like that "Lenny" says "Yeah" and similar positive type words from time to time; those crooks might claim that was an agreement to get a subscription to The Wisdum of L. Ron Hubbard crammed onto my phone bill.) My ideal would be to sound perfectly normal, do some interpretation of what they're saying to actually address things they say, and do a "curious about the product but not agreeing to anything" act for as long as they stay on the phone.
On the top of the blacklist are those evil <redacted> who call six times simultaneously, so the phone rings a whole lot longer than normal before going to voicemail, and the Caller-ID announces their name six times. Bastards. This is the sort of thing that makes me yearn for the "Scanners" power to reach down the phone line telekinetically and set their computer on fire.
Bonus, custom voicemail messages for appropriate callers, white/non/blacklisted. Like "Hi, Mom, we're not home, call my cell."
I told the "Microsoft Tech Support" crook "But I don't have a computer."
That apparently wasn't in his script; it took a while for that to register.
My wife was about to bust up laughing. After I hung up, she said "You lied!".
I said "No, I didn't. I don't have *a* computer. I have *a bunch of* computers.
Blipverts. High-speed advertisements so designed to get the advertiser's message embedded in your brain before you can grab the remote.
Ignore those silly rumors about it causing some susceptible people to explode...
I don't block ads. I don't have a problem with ads as such. I do block scripts unless I feel the domain has some degree of trustworthiness. No ad servers have any degree of trustworthiness whatsoever.
Sites like forbes.com, which will not show you anything but their "Give us carte blanche to ream you with malware laden ads or you can't see our domain" splash page can die in a fire for all I care. I'm not doing it.
And onions are deadly to dogs! Why do you hate America, onion eaters???
And Xylitol is even worse. Blood sugar crash and death if dogs eat it, and not much of it at that. But there at Whole Foods, a big bag of the "Wonderful all natural non-sugar sweetener", pure xylitol, and not a word on the bag about how Fido is going to die horribly if he gets ahold of any of it.
The Greens prefer fusion because it does not exist. Yet. If/when fusion does exist, it will get the full attention of the usual omni-obstructionists.
They're opposed to anything that produces energy on a scale sufficient to power industrial civilization. That's the issue. Energy that really is cheap, clean, and abundant? "Nothing short of a disaster" (Amory Lovins) "Like giving a machine gun to a retarded child" (Paul Ehrlich)
