Is the following info up-to-date?

I want to make money from scam calls, but the relevant info I can find is at best 2 years old.

What I want to know is:

Are the steps taken in this video still viable: https://www.youtube.com/watch?v=MP1R8KJ0Oo8

Is the information on the FTC’s website regarding penalties and the registry in general still accurate: National Do Not Call Registry FAQs | Consumer Advice

EDIT: Also, is this template still accurate to demand letters today, more or less: Example Of Demand Letter | wfmynews2.com

Thanks in advance for any help!
