Ohhh that drunk guy... I think most of us remember him all too well...Actually, the drunk guy was temporarily banned for verbal abuse.
As far as this topic goes though I'm in agreement with Vir. We can't control players language in the game, all we can do is block them and let there reputation come through till we see who they really are. I feel we've done a good job so far in who we allow, based on character, to be apart of endgame gear and bosses. All in all though we can't block people from entering the arena nor can we control the way they speak. We can only affect how far they progress in game. Also by the sounds of it, even though I've been on leave and not quite sure exactly who we speak of, they are now known and have been x'd out of our endgame fun. As far as the trouble they cause in arena, there's not always gonna be an endgame player there to deal with them on spot. All I can tell to the ones they are affecting is to continually contact a higher level to come to your aid to help. We've seen it many times before though and the ones who try and disrupt our peace in Lugh never last. They eventually realize that they can't go anywhere given the reputation they've gained and they always slowly just drop off... Or possibly build a new toon and never mention their old one and play by the peaceful rules we've established here in Lugh.
