I guess that makes sense. To be honest for me it's such a social experience who I'm playing with is the biggest thing I care about.

with randos off Discord or Roll20 and not actually in person with people they know.

I know online rpg changed a lot in 20 years, but when I was playing online around 2010, playing on teamspeak, also meant be part of community, and ask others GM about new players before having them joining your table (No show, cheating and other bad behaviour would quickly be known by everyone) . Moreover, because you don't know them, it's easy to kick them out.

so the jerk ratio is higher? genuine query, only played with friends irl
