Hiya,
Thanks for raising this issue. PlaneShift has seen more than its fair share of rude, moronic visitors during its lifetime. Usually they won\'t hang around for more than a day or two before finally realising that they\'re wasting their time. However, things like this are still highly annoying, and can make other players leave the game.
In future, if there is an abusive player causing trouble online, please visit the public developer IRC channel immediately and ask for an admin to check out the situation. They will join the server and witness it happening for themselves, and kick the player if necessary.
Currently, as MB is only a tech demo release, there are no measures to prevent things like this happening, nor indeed to do much about it if it does. However, there will be some basic features in CB which can help.
1. The /ignore player command. If a player is annoying you, you can simply ignore him.
2. GM presence. GMs will moderate the game world and can be alerted by players if there is trouble. GMs will take the appropriate action against the offending player (silence, kick, ban, etc).
I don\'t know of any plans to implement chat-censors, but this may also be worth considering if the situation were to ever start escalating. As it is, I don\'t really think this is needed right now. Most PS players are mature and take care to not offend people with abusive language.
