This is why I think it has to be someone else. I very much doubt that Chris forgot who Ian Brandon Anderson was, largely because weens keep yelling it at him in reference to an eight-year-old meme.
As for the other names, why would he put those? Chris has given shout-outs to terrible people before, but there's usually context or explanation, like when he thought the Columbine killers were Sonichu fans. Assuming Chris doesn't know who these people are, they're just random, mundane human names, specifically male ones.
