Friend requests are a problem. I have played on two very different servers, and on one, friend request spam was absolutely insane. This will definitely help servers which have this problem. Remember that just because you don't experience it doesn't mean that nobody else does.

However, for the servers that experience a lot more /tells, /shouts and /says, this isn't going to help any. They could certainly do more about the RMT's but I'm glad they've acknowledged them and taken a first step.
