I was livestreaming about a month ago and kept getting spam calls, so I decided to try to see what I could find out.

A website they pointed me to had a multidomain SSL certificate gave me a list of other scammy domains, and one that appeared to sell robocalling software. On that site I found a phone number to call to get started. I called the number and somebody immediately answered! I pretended to be an interested customer for a while, and he claimed to be the author of the software. I wasted his time for about 10 minutes asking questions about how it worked, and where i could get lists, etc. Then told him I wanted him to add a patch to prevent my number from being called again, and that I'd be calling him again if i got anymore calls.

It was very fun!
