Karma...What is karma?
Karma is being kind,and recieving kindness in return. There are probably many people who would see something like this as an opertunity to make the bungie forums fall to it's knees. However, as if to cancel that effect, there are those who would just like to go, " Hey I've got 71 points, you?"
" 21"
Then it would be left at that. No flamming, spamming, whatever. When people who work at companies see their forums, they are just too busy to look at every person to check if they are good. They probably check their friends list(if you are linked) and number of posts, locked forums posted in, that thing. With this "karma" thing, things would probably work out for the better, just some things would need to be changed.
Maybe there should be some kind of "aid button".
When pressed, a mod will look at the forum and see what is wrong soon as they are open. Either somebody being very bad, or somebody acting helpful and stuff. And if that happened, when somebody pressed the button, they would have to put a reason why they are, then the edit post button would be gone for that forum, so they can see it how it was. If there is no problem, that person will be in trouble and may be banned from forums or something. Course that would mean to prevent accidents, there would have to be a popup saying are you sure you want to contact a moderator to look at this thread" thing.
