Signing people up for research is more of an inside joke from way back in the forum days, I don't think many people say it literally, they either say it to be in the in-crowd, or as kind of like an inb4 thing since someone always says it when someone posts an e-mail, or just to scare the person a bit. Also how he was acting justified being mean to him because even though he has autism I still am pretty sure he was trying to troll in a stupid 10 year old kind of way. I don't think autism makes you get stuck on caps or become hellbent on doing things that would annoy the community.
