I used to hunt down, expose and try and shame scammers in peer to peer Bitcoin lending platforms like BTC Jam and Bit Lending Club.

A Russian and I created a website called shameless which loaded all defaults in one place and exposed the shameful.

These loans were regularly 50 BTC.

It was fun at the time, but it took a lot to keep doing it. After about 2 years, I did come away with more Bitcoin. But, it should have been much much more.

Also people didn't like to be told they were lending btc to a scammed, it was mostly worse than a thankless task. This was all as me Joe Bloggs, same icon etc, so I'm not exposing any new information.
