A system that permits you to vote someone down tends to be a bad thing in general. Its too easily abused.

One sort of system that might work well is one that is based around giving good RPer votes. Including the ability to pull back the vote later. Not sure whether such a system would be optimal to have with or without the ability to see who approved of him/her. Its more open with the ability to check "supporters", while a closed system might promote some few to create accounts simply to vote up themselves.

But even this is open for abuse. Some elitists may start having "Only players with 10+ votes permitted".

Thoughts?
