Getting more calls after signing up on the Do Not Call List

I used to work with systems that had those 8" floppies. The 5-1/4 was a nice improvement. Soon people won't even know what the 3-1/2 ones are for.  I thought it was funny that he used an acoustic modem to war-dial with. Does he have a separate circuit connected to the phone line to operate the switch-hook?

Both sides of this argument have a valid point.
It seems that the DNC list reduces your exposure to 'legitimate telemarketers' but increases you exposure to foreign criminal scams.
I was able to do a simple comparison for about 4 years.
I had a DNC listed phone and one that was not listed.
On the DNC listed phone I did not get 'legitimate' telemarketers - companies trying to sell to me or 'lead hunter', but I did get a large number of absolute criminal scammers - mostly foreign via the internet.
On the non-listed phone I got a scattering of legitimate (but annoying) telemarketers, but fewer of the foreign criminals.
In the long run, I got more annoying calls on the DNC listed phone, but at least I knew 'a priori' that they were criminal scum.
On the listed phone, nearly every caller agreed to put me on their internal 'do not call' list when asked - as required by law.  On the other phone, they laugh and cuss at you when you ask to be removed - because they are criminals sitting safely in Mumbai or wherever.
I think this happens because a company, or a front company for criminals - can buy a regional listing of DNC listed phone numbers.  The broader and larger the list the more it costs, but it is can be less than a penny per number.  This is how legitimate telemarketers know not to call you, they buy the list and block them off their calling list.  But in the hands of criminals it becomes a list of valid phone numbers that can be sold to whoever wants a pre-screened list of potential victims.  They can buy the lists and sell them at a discount to multiple scammers and make good money on their investment.  They may sell the list to dozens or hundreds of foreign scammers that then call us, and the 'list buyer' has no risk.
It would be interesting if some university got a contract to do a more comprehensive study like this with more phones, with different usages, for a longer time - with proper record-keeping.

It has been said many times on this site -- why on earth would scammers want to specifically target numbers of people that have gone out of their way to indicate that they do not want calls?  Why go to that trouble and expense when an autodialer can just call numbers in succession?

>>  But in the hands of criminals it becomes a list of valid phone numbers that can be sold to whoever wants a pre-screened list of potential victims.  <<

Think harder.
It is a list of people who are known  to NOT want sales calls.  It is a list of the worst "clients" or "suckers" around.  It is a list of people most likely to hang up, and least likely to buy from a telemarketer.

Also, a "war dialer" (sequential or auto dialer) is comparatively cheap.  Such dialers attempt to reach a broader selection of phone owners.  After all, numbers are no longer secrets.

Yes I am sure you are right.  After all what says definite sale more than a $16,000 list of people who don’t want to be called and probably will not buy anything if they are.  Maybe their business strategy is that they love a challenge?

Now, I guess you failed to read my prior posts?  Or you didn't want to know the truth because it would make your theory wrong?  You see I listed a number on the DNC that wasn't listed before.  I had 23 calls in they year and few months prior to listing.  Since I listed on January 23rd of this year, I have had 5 calls from crooks that have called me prior to listing.  But see here is the thing.  I watch who i give the number out to.  I don't publish it on social media.  I haven't found it listed under my name on those wonderful web sites that publish all your info without your permission.  So no doubt there is a big difference between the number you are talking about and my number.

I also did the same thing as you.. I had a phone number that was getting 1 bad call maybe 2 a week without being on the DNC List... I had this same number for a year. Two months ago I decided to investigate this concern and registered my phone number to the DNC list. I made sure not to give my phone number out to anybody else besides the DNC, kept it clean. Within 30 days I started getting scamming calls 1-3 times a day. The amount of bad calls went up ten fold! This can be a coincidence but it is just not very likely.. I didn't contaminate the experiment with any other factors. The facts from my experiment are, #1 Registered to DNC, #2 Bad Calls went up exponentially. I have no agenda, but it seemed like the person BigA had an agenda from the start, you can tell he wanted to prove himself right.

>>  I have no agenda, but it seemed like the person BigA had an agenda from the start, you can tell he wanted to prove himself right.  <<

Um ...
You claim you have no agenda, but you also state BigA (a registered member who routinely posts good information)  has an agenda.  Your agenda seems to be belittling BigA's post.

Given the above, I think I will believe BigA's statements rather than yours.  After all, it is MUCH less expensive to use a war dialer, than to spend over $16,000 for a list of numbers of people who do not want telemarketing calls!

The only one with an agenda here is you-and that's to be a troll

"I have no agenda, but it seemed like the person BigA had an agenda from the start, you can tell he wanted to prove himself right."  I see, so I wanted to prove myself right but you don't?  Wouldn't that negate your post?  Sorry but I don't believe one word of your post, much like you don't believe one word of my post.  I however have the data to prove what I say.  Do you?  Do you have the data of over a year carefully logged and documented?  I doubt it.  Further, my number never got 1 bad call every two weeks.  Which means they had your number well before you signed up for the DNC.  I did expect on of you scammers to try to come here to try to prove that I was wrong because it hurts your pocketbook having people sign up.

The number of calls you get from scammers is a function of how many scammers there are to talk on the phones and how many calls their equipment can make while waiting for someone to answer the phone.
AND their giving up calling in other area codes + exchanges because people won't answer their phones, or aren't home to answer their landline phones, or call blockers grab the call and hang up on it.

For the first six-and-a-half months of this year, I rarely got any calls from scammers, an average of 10 to 12 a month; many days my phone did not ring with a call from a scammer. I can check call logs online on my Uverse account so I knew just how many calls were coming in without having to copy anything from the Caller ID display.

But something changed two weeks ago, on Monday, July 18. I got six calls that day, and every day afterwards five or more calls each day, except on Sundays. Many of the calls have my area code in them; before, most calls did not have my area code, or an area code geographically next to mine. These new numbers never leave messages on the voice mail, after letting the phone ring four times. For the past two weeks, the only voice mails I got were family and friends.

And these new numbers had no complaints on 800notes prior to me getting a call from them. I don't know if the scammers have actual numbers in this area code (through VOIP like Magic Jack, Vonage, Google Voice, etc.) or if the numbers are spoofed.

The number of ASSUMPTIONS here is Incredible. Then there's the logical fallacies...

You've never been one to talk

At the start of summer, the rate of my nuisance telemarketer calls shot up and has been high ever since. If I had registered with NDNCR a month prior instead of from the start of the program, I might have drawn a false conclusion from that.

Better data than most, but a sample size of two vs one is not really a significant improvement. A sample size of two is not an experiment; it's a coin-toss.

I agree it would be interesting if some agency tried an experiment with a sample size large enough to mean something. Preferably with known virgin phone numbers.
