Not really, least in my experience.

I’ve had spammers call me a few times. Now what did work, was when I got personal with them. I haven’t gotten a spam call in a few months now. It’s bliss.

Don’t feel guilty treating these people like shit, they chose to do this. People try framing it all like “they were forced to by crazy psycho bosses! have mercy!” Nah, even if that wasn’t the case…they still willingly chose to do this.
