I'm not surprised that a haphazardly organized group of people /can/ run a site like rarbg. It's just interesting how volatile (this isn't the right word but I'm not sure what is) the operations of these sites tend to be in light of the fact that the sites hold a lot of cultural value. RARBG was incredibly popular and was an important resource for torrenting. It's rare to see sites of that size and importance run in that way these days.
Radical notion these days. Everybody has an ulterior motive, probably one you find offensive, and you have to read between the lines and make uncharitable assumptions about their motives to find them out.
