The game under discussion doesn't collect PII, and all personal information was freely published by Hamill himself, so there's really no problem here. However, the same would not be true of most similar circumstances, and I'm encouraged that at least some people are aware of the issue.
We need to think about this non-issue and warn people about this non-issue and dissuade people or possibly even implement policies for this non issue just in case it ever becomes an actual issue!
