1. He was closer than any other projection, so disagree here.
2. Okay
3. What would make Chris a serial scammer?
4. He wrote an algorithm that tracks bot activity on Twitter, then was subsequently banned from using the Twitter API for his disclosure of said bot activity across the platform. Is that why you consider him a scammer?
I've spent more than 5 minutes looking into his profile and past history/exploits. I've yet to uncover a single detail that helps to underline your claims of him being a scammer/grifter. If it was that obvious, it would be.
