Agreed. The only people that could drop meaningful lore (or rather "khantext") at this point are:
- DSP's parents/relatives (never going to happen)
- Some random faggot who went to elementary/high school with him and realized how "famous" he is now
Both of those are extremely unlikely to happen though. There are thousands upon thousands of videos and feature length documentaries about "the guy" and no one has ever popped up.
The other possibility is someone does deep dive research and contacts his teachers/people who went to his school - but my hunch is that DSP was totally unremarkable in every way possible until he got internet/YouTube famous and was probably pretty quiet and shy so no one would remember shit.
You would assume that as the valedictorian someone would remember "the guy" but that has never happened.
