I disagree.  People go on tirades against others.  If the "other" is not monitoring 200 then he/she could be made to look very bad without the ability to give a different perspective.  If we could somehow filter out attacks on other players then I would agree.  
I personally find 200 somewhat entertaining but I'm starting to question if the cost outweighs it's benefit.  Perhaps not allow someone to type to the buffer on channel 200 for a 2 minute period after they die.  Dead people don't talk. 

   Actually, it's a cool down period.  It might elimiate some of the HO messages and insults which cause much of the clutter.
I also think you should have to request a PM to open a communication channel with another player.  The other player should be able to refuse it.  
I think 200 is good.  I think the personal attacks are bad.  We should focus on ways to help reduce the personal attacks.
