It's probably because there's about four people who regularly go to 73q, and so I guess if there were a hopper there, it'd be even more ignored than the one here.

73Q doesn't have a hopper because presumably Chet assumes no one would do something that fucking stupid and it's stupid to have a hopper for music videos since it means every douchebag with different tastes would just vote everything down. Half the shit on there right now would never have made it with a hopper system.
The few times someone has spammed or abused 73Q, it's usually taken care of itself by being one-starred off the front page and the person caught enough shit for it that they never did it again. If someone went REALLY far, I'm sure Chet would just ban them if it really got to that sad of a point.

I like my explanation better.

I feel like you're missing some key details here, including who/what The Monkees, in any incarnation, were about.

Holy crap, you made me look up what The New Monkees is about and I can't believe I've never heard of this before.

"On the show, the band lived in a large mansion with a butler, and numerous unexplored rooms (much like recent hit series The Young Ones), and this was the main source of their adventures. Instead of a normal kitchen and dining room, the house featured a diner with a waitress."

We got lost in our house again! At least there's hairspray in every room.

No, no. The only thing you can hope for now is to spread the infection to as many others as you can, to ease your suffering by creating a legion of those who had this fucking nonsense inflicted upon them.
