If by "shill" you mean someone who has volunteered thousands of hours and years of my life to help grow Bitcoin into a global peer-to-peer electronic cash system, then here are some of the ways I've "shilled":

1. In 2014, I developed the first ECDSA signing tool capable of signing Bitcoin transactions offline over an air-gap by drawing power from the NFC field [video].

2. In 2015, I co-founded (and still co-manage) the first peer-reviewed scholarly journal for Bitcoin and blockchain research, Ledger.  

3. Also in 2015, I did research to demonstrate that a transaction fee market would exist without a block size limit [paper] [video]

4. In 2016, I co-founded Bitcoin Unlimited, which is now a $10 million+ organization that supports Bitcoin research and outreach across the world.

5. Also in 2016, I did research to show that with subchains, bitcoin's transaction capacity could be increased while also providing faster TX verification by miners to users [paper] [video]

6. In 2017, I demonstrated a security weakness in segregated witness [[ur=https://www.youtube.com/watch?v=VoFb3mcxluY]video[/url]]

7. Also in 2017, I spearheaded the launch of the $3 million "Gigablock Testnet Initiative" and presented our initial result in Stanford [video]

I have done all this to date as a volunteer because I love bitcoin and hope to see it change the world for the better.
