Instead of Cheers/Jeers, we could have Pax/Pox.
With each Pax, the poster's avatar would get shinier and shinier via an excruciatingly exact backlit effect. This would be the clear light of nature.
With each Pox, the poster's avatar would get more diseased--tiny red pixels of pustulating pox.
At the end of the month, the poster with the shiniest avatar would win...something: Transcendence, perhaps.
The poster with the most diseased-looking avatar would be banned, and good riddance to another pox-addled poster.
