Surely everyone can get along but we each have someone we don't like to hear from time to time or at all. The /ignore in game feature has proven to be a very useful tool for those we have had enough of. Though this does not prevent them from sending you a private message via Forums. This could work like the block feature that most other social media sites use. Such as you can go to their profile, select block, then they cannot view your profile, send you a message , or see what you are viewing (though this last part is already in feature just on a more grand scale). I think this would work great and prevent much more future conflicts between players beyond in game. Though this feature would not work against player --> Staff Member since Staff members need a way of reaching you as their authority will allow them to. Please take time to read this. If this is not possible with this Forum type then oh well :S
