This is how I feel about the situation too. If people would like to see more serious discussion in GC, please warn the spam posts and we'll handle it. We try our best to keep it decent, but we can't catch all of it.

I don't mind deleting some spam posts, but what bothers me most is when the same people continue to act that way after their previous spam has been deleted. Your posts being deleted should be a pretty clear indication that that type of content is not welcome, yet members don't seem to react that way. Either they are too dumb to get that or they just don't have much respect for the rules. Maybe an announcement should be made to clear this issue up.
