Why should some sonofabitch profit by being able to mud when others have coded
the game for them?

I think this thread has been discussed before, and I think that several people
suggested several things which an intelligent highbie can implement in order
to prevent such problems. Put dimdoors in a 'safe' place, use shelters, etc,
dont use dimdoors, accept the costs, whatever. If you're not intelligent
enough to come up with workarounds for a feature of the game, then why are you
mudding here?
There are many aspects to the game which allow one mudder to steal benefit
from the skills/experience/abilities of the more expensive players. It's a fun
aspect to the game, and can be a very memorable thing for a newbie who entered
some random dimension and found himself up against that big monster that hes
seen tons of other big highbies fighting and dying to before.
