Killing spam won't increase the spam elsewhere... It'll only make people forget about it and look more into fangames and such...
You realise, you're entirely incorrect.
Not allowing users to spam in an area, makes the jobs of moderators and administrators a lot harder to deal with.
If there is an area where people can let things out and act weird, its best to allow them to do so, then they wont spam up other areas of the forum, quiet as much.
Spam is something very hard to get under control in most situations, I think we do pretty well to control it here. There will be times when it slips out of our reach, and I'm sure we could do a lot better than we are doing now. We always need reforms, and we need to look at things in another view point sometimes. We're looking at other ways to improve our current spam policies as they are.
It will take time, but we'll clean up. For now I think we're doing a lot better than most places.
