Can we have chat delay on global channels? Primarily Trade and LookingForGroup. World is effectively policed already by the public activity and function like a chat channel so that one should probably be as it is. The other's however are often spammed and it's really unnecessary.
I could go on about using LookingForGroup for trade and guild advertisement, but that's a different issue that require active policing.
And sure it could be argued that guild advertisement have a place in LFG, even though I wouldn't favour it when there is a guild recruitment channel unguilded are automatically put into. And new players unfamiliar with how to find a guild are not likely to be on LFG channel anyway. And those who are on LFG channel are more experienced and do not need the advertisement.
