Well, I have an idea that gives meaning to Karma, and could stop the flooding of the general chat. I was playing perfect worls, and I was going around slaying beasties with my venomancer when I saw something that caught my eye in the general chat on PWI. They were talking about teles or whatever they are. I can't remember the exact detail, but I DO know that you can not post in general without purchusing these tele's, as far as I know.
So, my lame and never going to get used idea (I'm putting it here to see what you think) is what if karma was like these tele's? You need Karma in order to be able to post on the general chat. It would stop a lot of spamming, because a majority of the trolls and spammers probably never go on the forum and wouldn't have the Karma for it.
I know this idea isn't too good, if there was ever a slim chance of it working it would need a lot of improvements from simply karma means you can general, and a lot of people probably wouldn't like the idea, but I just thought it could help with the spamming issue, and give people a reason for their karma...
