I honestly don't even see the point. It's not like you're missing out on a juicy conversation.. nobody talks.
In case you haven't noticed, there are these little icons to the left of players' names. This indicates they're in a Linkshell, a social group of members who often talk to each other, quest together, help each other, etc. I'm sorry you have no one to talk to but try joining a LS, and whenever anyone types anything it'll disappear from your chatlog in mere seconds thanks to crafting spam.
