Spam hell, can i just /hide or block all tells?

[Ogulbuk]

As the title says: is there a way I can block all tells, or appear offline so I can stop the RMT spam? Best I found so far is how to disable the tell noise. Ideally, would love if I was just able to tell the game to not deliver any tells from people that are not in my friend list.

There are a couple of things you can do:

1. Just remove the tells from your chat feed completely. It doesn't block them but you don't see them.
2. Go /busy. That will prevent anyone from sending you a tell.

If you go /busy you might want to leave a comment in your status that you have blocked tells in case someone actually wants to talk to you.
