1/ For those of you who don't support the PCs but have been wondering how "Sarah" got your number, here's a PSA:

2/ The list comes from the Canadian Numbering Administrator & it's publicly available. People accessing this list receive the area code + first three digits of a phone number. For example, 647-484-XXXX. After that, it's guesswork: 0000, 0001,etc. That's why even Jagmeet got this:

3/ As the robocaller dials all possible combinations of the last 4 digits, a computer waits for your response. If you respond at all, they now know that your number is real and that information gets put into their database.

4/ Some people have tried to trick the algorithm with false responses. Again, ANY response provides valuable information to the PCs. Whether your response is positive, negative, VERY negative, or otherwise it helps their algorithm improve itself.

5/ In the era of big data, we don't know how this information is being used.

My suggestions:

1) Don't reply at all.
2) Don't reply at all.
