How can I receive more calls from scammers and telemarketers?

Many of my friends often complain about how they receive so many calls from scammers, telemarketers, autodialers, etc. I receive maybe one per week at this point. If I call some of the technical support scams, I will start receiving a bunch for a week but they all drop off after that.

I removed myself from the FTC's Do Not Call list hoping that would attract more callers, but it hasn't.

Can anyone suggest some good ways to receive unsolicited calls from telemarketers, scammers, etc.? I'm sure many people would love to not receive so many of these calls, and here I am asking for more. ;) Thank you!
