Solution to Zero-Bombing in the Audio Portal, and Improvement to the Rating System in General
Right now, you have two rating systems for both the flash and audio portals - the two systems being the 5-star system (with the faces) and the 10-star review system. Why do we need two systems?
Scrap the 5-star review system and keep the 10-star review system. In rating, they will also be reviewing and thereby revealing themselves. Their votes are not anonymous, so any bad or unfair rating is more detectable and they are more likely to be punished for engaging in such behavior (i.e. whether by mods temporarily banning them from reviewing, or by other users deciding to give this user bad reviews in return). Thus, they are also more likely to refrain from this behavior.
I'm still not sure what the point of having the 5-star system is when we already have the 10-star system. Someone please explain this to me. "The 5-star system has the faces so it looks cool" you may say. Okay, well if you want to keep the faces then just move them to the review section (have the faces there instead of the stars), and possibly change the review scale from 10 to 5 (there's no need for 10 rankings, honestly).
