Why can't we have the same anti-spam feature that WoW has?

Receiving spam every 20-30 mins is indicating of a broken system. This is not something we should have to tolerate in an MMO in the same way we have to tolerate other unsavory people.

I was online most of the night yesterday and got maybe 1 tell. And last I checked they dont spam in /shout at all anymore.

They are working on it. Fighting RMT spam is a neverending battle, heck wow has been around for nearly a decade and they still have RMT spam.
