I actually lost about $5k on cheapETH running servers. Nobody was "defrauded", I think these people don't understand how forks work. It's a precursor to the modern L2 stuff, I did this while writing the first version of Optimism's fraud prover. https://github.com/ethereum-optimism/cannon

I suspect most of the people who bring this up don't like me for other reasons, but with this they think they have something to latch on to. Doesn't matter that it isn't true and there wasn't a scam, they aren't going to look into it since it agrees with their narrative.
