Personally I think seeing pk beef on yell is very good for the server, example:
Some new pker joins, see's active clan beef on yell, thinks "Oh pking is actually active on here great", "theres active clanning scenes" etc.
I dont even see a need for a 2nd yell, Just needs to be fairly moderated and staff members need to stop being bitches and handing out punishments for pk beef. When it gets to actual flame, yes then punish/make it stop, but pk beef/banter on yell is actually very good for the server if you exclude the snowflakes that get upset over anything and everything.
