I'm just throwing in my $.02 about this subject.
I don't use kill stories alot but I like to see what kind of kills are being posted. I might question a kill that seems to good to be true sometimes but I try to do it in a constructive way. I don't get many street races but when I do I'll:
1) Go to a safe location or do it as safe as possible
2) Post it when it happens and if I get BS responses take it in stride ask questions and restate the facts and look at the situation.
From what I'm reading is that it'* to much trouble for the Admin to watch and enforce. I can see why, with 3 moderators and 2 admin to cover the whole board they're overloaded. I've also noticed in the threads that are locked that it seems like the same individuals are involved.
Get more Moderators. Give them specific areas of responsibility so they don't have to roam the whole board looking for trouble. The most that each Moderator should have responsibility over should be 5 or 6 Forums. You can have 2-3 Moderators per Forum and they can also Moderate other forums when necessary but their primary ones will have their names by them.
Also start punishing offenders. Warn them VIA Private Message, Warn them Openly,Blur their post, Ban them temporarily or permenantly.
At least I have a positive attitude about my destructive habits.
