Rmt spamming has definitely gotten better over the past months, but, it could still get better.
A lot of the times when logging in for the night, one of the first tells I'll receive isn't from friends its RMT spam. And there really has been less of it due to the addition of the add to blacklist feature in the game, but I (in my own personal opinion) think more can be done.

SE should have GM's for every server monitoring for RMT, and other harrassment issues for one thing.
Adding a feature where the add to blacklist also reports the person that was just blacklisted.
Also I think that if you blacklist someone on one character it should be account wide, (if you have multiple characters.)

Any thoughts?
