Pretty sure this is made up.

1. How would the scammer know they were the ones who posted their number on Craigslist.
2. Scammer's number is usually a spoof. Not the actual number.

As I like a good scammer scamming, they use spoofing technique to masked their real numbers. So don’t do that

Aren't those numbers typically just from servers rather than an actual SIM card in a physical phone?

You can report scammers to the FTC using your number and the time of the call, as well as their number, name, and any additional information:

I highly recommend this because, believe it or not, these scammers do get caught. The sooner the better, they can do irreparable harm in the meantime to people more vulnerable than you.

There isn't a person sitting on a phone sending thousands of texts. These are spoofed numbers. There is no human on the other end whose phone will get inundated with calls if you post their number online.

Scam calls and texts always use call ID spoofing. Blocking them would be easy if they used their actual number.

And now you're banned from Craigslist.

As others have said, there is no way those scam/spam messages are actually coming from that number.

again, an instance of funny proves tech illiteracy and boundless idiocy

Great idea
