I mean in the case of unexcused absences; just disappearing with no word or comment about when, if ever, they'll be back. It's understandable that unexpected things happen and people are busy sometimes, but why join the rp in the first place if you won't have time to put in the effort it requires? Like all rating systems, there's the possibility of abuse, yet for the majority of cases it works fine. It's like a youtube video; no matter how good it is, theres always some douche that gives it a dislike just to disagree with everyone. One bad rating isn't going to phase a dozen good ones. I still say yay for the User Reliability rating system.
