It's much easier than you think for anyone to embark on a scamming robocall campaign.

All it takes is a simple online search to find a service that will let you call millions of people, and there isn't much regulation on what kinds of services you can find online.

Some of those services are perfectly legitimate, and can be used for legal and legitimate robocalls.

Others turn a blind eye to scammers.

For the longest time, I pictured robocall scammers in a dark, damp room using some kind of seedy custom software that was probably bought from the dark web to make the billions of robo-scam-calls that Americans receive each year.

Indeed, according to robocall blocking service YouMail, Americans received 4.35 billion robocalls in June alone. And that's almost a billion less than the number of robocalls in April, when Americans received 5.23 billion robocalls.

For some spammers, my imagined spammer HQ may be perfectly accurate.

But if you wanted to moonlight as a robocall spammer without delving in the depths of the dark web, you could just do a quick search online.

Indeed, just search for "robocalling services" on a search engine like Google or Bing, click on one of the results, setup an account, pay, and off you go. Right now, right from where you're sitting. Then, if I get a hit from an unsuspecting victim from the millions of calls I made, I can get on the phone and work my magic to extract sensitive information, or convince them to hand over money.

When I asked Jim Tyrrell, senior marketing leader at networking services firm Transaction Network Services, if it really was that easy, he replied "You're absolutely right," adding that "unfortunately, it doesn't cost a lot to set up an operation like that," and that it can be an extremely lucrative endeavor.

Interestingly, the first few results on search engines are promoted results for robocalling services. With that said, those promoted results for robocalling services are more likely to be reputable robocalling services.

That's right. Reputable robocalling services.
