Reminds me of "scam baiting" which is becoming a popular live stream opportunity.

I occasionally watch this guy who calls tech-support scammers or IRS scammers and attempts to waste as much of their time as possible. He will often impersonate an old lady using a voice modulator (or he'll implement other personalities) to make his performance more realistic. It can be quite entertaining.
