Multiple? Or every? Have you been to a Maryland Tarapins forum? How about San Diego State University?
My point... I don't like the umbrella statement that all other schools have this same problem or worse. Nobody knows that is a fact. The schools that you probably have spent time on are probably the boards where school reputation and prestige are enough to offset the perception of the fanbase.
I would say our board is probably the best in the Big 12. Maybe Phog.net is better. KSU, UT, OU, OSU, Baylor, A&M, MU, and NU's that I've been on are all way worse. I can't find anybody who cares about CU online. TT has a pretty decent board but there was just some awful stuff on there after the Pirate was let go.
