I put myself down for Somewhat Negative. I hate them as a Big 10 West Div hawk rival and how they think they are so much better than Iowa. But I didnt hate them a long time ago unless they played my favored teams like Iowa, Ia St (I was at the great IA ST tie game at old Clyde Williams field in 1973 iirc), or if they played Big 10 teams.
I almost always or always pulled for them to beat the southern teams during the 70's-80's and even up until now. If they played Arkansas in a bowl, I know laugh laugh laugh, I would pull for Nebby as a Big 10 team. Nebby played in so many Orange Bowls etc back in the day against SEC and ACC teams so I pulled for Nebby, the northern team, and even would pull for OU a midwest Big 8 team, against the SEC.
Nebby never seemed to be a cheating team but Osborne did sell his soul to the devil to get a Natty Champ and keep winning so I do think negative of that 10 year stretch. The change in schollie numbers rules and not allowing Nebraska booster clubs to pay for kids to walk on really hurt them over the years but that is ok. They still get a ton of walk-ons.
